Very rarely a segfault would occur when removing a number of packages
due to a corrupted list for the local database (FS#27805, FS#28195).
This was caused by the alpm_list_msort function not correctly dealing
with the two new head node's prev values.

This is particularly important in the case of FTP control connections,
which may be closed by rogue NAT/firewall devices detecting idle

Was able to get my hands on one of these boxes today, so add yet another
new way of doing this. I'm glad these calls are so standardized. This
was compile tested on Linux and Illumos and seems to still be working in
both places.

We lost this logic somewhere between the libfetch and libcurl
transition, as it existed in the internal downloader, but was pulled
back only into the sync workflow. Add a helper function that will let us
check for existance in the filecache prior to calling the downloader.

PGP keyservers are pieces of sh** when it comes to searching for
subkeys, and only allow it if you submit an 8-character fingerprint
rather than the recommended and less chance of collision 16-character
fingerprint.
Add a second remote lookup for the 8-character version of a key ID if we
don't find anything the first time we look up the key. This fixes
FS#27612 and the deficiency has been sent upstream to the GnuPG users
mailing list as well.

When doing a bare -U operation on a local package that doesn't pull in
any dependencies from the sync databases, we can get away with missing
database files. This makes the check conditional on no sync targets
found in the target list. This is not the prettiest code here so we have
a bit of hackish behavior required to straighten both the behavior and
the nonsensical error message out.
Addresses FS#26899.

The point of this early compare to NULL byte check was so we could bail
early and skip the strcmp() call. Given we weren't doing the check
right, this never exited early. Fix it to work as intended.

This takes the place of three previously used constants:
ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE.
In libarchive 3.0, the first constant will be no more, so we can ensure
we are forward-compatible by removing our usage of it now. The rest are
unified for consistency.
By default, we will use the value of BUFSIZ provided by <stdio.h>, which
is 8192 on Linux. If that is undefined, a default value is provided.

There aretwo seperate issues in the same block of file conflict
checking code here:
1) If realpath errored, such as when a symlink was broken, we would call
'continue' rather than simply exit this particular method of
resolution. This was likely just a copy-paste mistake as the previous
resolving steps all use loops where continue makes sense. Refactor
the check so we only proceed if realpath is successful, and continue
with the rest of the checks either way.
2) The real problem this code was trying to solve was canonicalizing
path component (e.g., directory) symlinks. The final component, if
not a directory, should not be handled at all in this loop. Add a
!S_ISLNK() condition to the loop so we only call this for real files.
There are few other small cleanups to the debug messages that I made
while debugging this problem- we don't need to keep printing the file
name, and ensure every block that sets resolved_conflict to true prints
a debug message so we know how it was resolved.
This fixes the expected failures from symlink010.py and symlink011.py,
while still ensuring the fix for fileconflict007.py works.

There is some pecular behavior going on here when a package is loaded
that has no files, as is very common in our test suite. When we enter
the realloc/sort code, a package without files will call the following:
files = realloc(NULL, 0);
One would assume this is a no-op, returning a NULL pointer, but that is
not the case and valgrind later reports we are leaking memory. Fix the
whole thing by skipping the reallocation and sort steps if the pointer
is NULL, as we have nothing to do.
Note that the package still gets marked as 'files loaded', becuase
although there were none, we tried and were successful.

This adds a logger to the CURLE_OK case so we can always know the return
code if it was >= 400, and debug log it regardless. Also adjust another
logger to use the cURL error message directly, as well as use fstat()
when we have an open file handle rather than stat().

The absolutely terrible part about this is the failure on GPGME's part
to distinguish between "key not found" and "keyserver timeout". Instead,
it returns the same silly GPG_ERR_EOF in both cases (why isn't
GPG_ERR_TIMEOUT being used?), leaving us helpless to tell them apart.
Spit out a generic enough error message that covers both cases;
unfortunately we can't provide much guidance to the user because we
aren't sure what actually happened.

This is in the realm of "probably not going to happen", but if someone
were to translate "disk" to a string longer than 256 characters, we
would have a smashed/corrupted stack due to our unchecked strcpy() call.
Rework the function to always length-check the value we copy into the
hostname buffer, and do it with memcpy rather than the more cumbersome
and unnecessary snprintf.
Finally, move the magic 256 value into a constant and pass it into the
function which is going to get inlined anyway.

In the default configuration, we can enter the signing code but still
have nothing to do with GPGME- for example, if database signatures are
optional but none are present. Delay initialization of GPGME until we
know there is a signature file present or we were passed base64-encoded
data.
This also makes debugging with valgrind a lot easier as you don't have
to deal with all the GPGME error noise because their code leaks like a
sieve.

Similar to what we did in edd9ed6a, disconnect the relationship with our
stack allocated error buffer from the curl handle. Just as an FTP
connection might have some network chatter on teardown causing the
progress callback to be triggered, we might also hit an error condition
that causes curl to write to our (now out of scope) error buffer.
I'm unable to reproduce FS#26327, but I have a suspicion that this
should fix it.

This is a poor place for it, and it will likely move again in the

This was done to squash a memory leak in the sync database download
code. When we downloaded a database and then reused the payload struct,
we could find ourselves calling get_fullpath() for the signatures and
overwriting non-freed values we had left over from the database
download.
Refactor the payload_free function into a payload_reset function that we
can call that does NOT free the payload itself, so we can reuse payload
structs. This also allows us to move the payload to the stack in some
call paths, relieving us of the need to alloc space.

Rather than always initializing it on any handle creation. There are
several frontend operations (search, info, etc.) that never need the
download code, so spending time initializing this every single time is a
bit silly. This makes it a bit more like the GPGME code init path.

Rather than free them right away, keep the list on the transaction as
we already do with add and remove lists. This is necessary because we
may be manipulating pointers the frontend needs to refer to packages,
and we are breaking our contract as stated in the alpm_add_pkg()
documentation of only freeing packages at the end of a transaction.
This fixes an issue found when refactoring the package list display
code.

No wonder these were slower than expected. We were only reading 4
(32-bit) or 8 (64-bit) bytes at a time and feeding it to the hash
functions. Define a buffer size constant and use it correctly so we feed
8K at a time into the hashing algorithm.
This cut one larger `-Sw --noconfirm` operation, with nothing to
actually download so only timing integrity, from 3.3s to 1.7s.
This has been broken since the original commit eba521913d6 introducing
OpenSSL usage for crypto hash functions. Boy do I feel stupid.

In the sync code, we explicitly allocated a string for this field, while
in the dload code itself it was filled in with a pointer to another
string. This led to a memory leak in the sync download case.
Make remote_name non-const and always explicitly allocate it. This patch
ensures this as well as uses malloc + snprintf (rather than calloc) in
several codepaths, and eliminates the only use of PATH_MAX in the
download code.

This commit was made with the intent of displaying "correctly" sorted
package lists to users. Here are some reasons I think this is incorrect:
* It is done in the wrong place. If a frontend application wants to show
a different order of packages dependent on locale, it should do that
on its own.
* Even if one wants a locale-specific order, almost all package names
are all ASCII and language agnostic, so this different comparison
makes little sense and may serve only to confuse people.
* _alpm_pkg_cmp was unlike any other comparator function. None of the
rest had any dependency on anything but the content of the structs
being compared (e.g., they only used strcmp() or other basic
comparison operators).
This reverts commit 3e4d2c3aa65416487939148828afb385de2ee146.
