* src/longlong.h: Restrict some HPPA assembly variants to PA RISC V2.0.
Note we also avoid this assembly for ilp32 runtimes, since even though
the assembly is accepted there, it's not safe as the context can get
clobbered between the 'add' and 'add,dc'.
This fixes a compile failure with newer HPPA systems with default
GCC CPU options.

src/factor.c (__GMP_DECLSPEC): Move back from longlong.h
to treat consistently with other stub macros.
(__GMP_GNUC_PREREQ): Reference to avoid -Wunused-macros warning.
(__GMP_DECLSPEC): Likewise.
(ASSERT): Likewise.
(__clz_tab): Likewise.
(factor_using_division): Mark a variable as unused.
(mulredc): Likewise.
(mulredc2): Likewise.
(divexact_21): Likewise.

* src/longlong.h: Restrict some sparc assembly variants
to sparc V9. This was seen to be an issue with newer
sparc systems with default gcc CPU options.

* src/factor.c: Renamed from factor-ng.c, with the following changes:
Adjust copyright header to be consistent with others.
Use xmalloc and xrealloc, to avoid segv upon OOM.
Switch back to using readtokens to handle input.
Diagnose invalid inputs.
s/fprintf+exit/error/
(print_factors): Add comments.
(strto2uintmax): Return strtol_error, not int.
(read_item): Remove, no longer used.
(main): Use atexit(close_stdout) so that we don't ignore failed write.
* cfg.mk: Exempt src/longlong.h from several tests.
Exempt run.sh from the test-list-consistency test.
Exempt make-prime-list.c from numerous tests, since we won't
be making it conform: it must not link with libcoreutils.a.
Exempt factor-ng.c from the no-upper-case error message test.
* AUTHORS (factor): Add Torbjörn and Niels.
* tests/local.mk (factor_tests): Encode the 37 tests.
($(factor_tests)): Rule to generate a test script for each test.
* tests/factor/run.sh: New script, marked as very expensive.
* .gitignore: Ignore new generated files.
* src/local.mk (src/primes.h): New rule.
(noinst_PROGRAMS): Add make-prime-list.
(noinst_HEADERS): Add longlong.h.
Remove all wheel-related rules and files.
* src/wheel-gen.pl: Remove file.
maint: mark set-but-not-used variables with ATTRIBUTE_UNUSED
* src/factor-ng.c (redcify, prime_p, isqrt2): Mark them, so we
don't have to disable -Wunused-but-set-variable.
maint: use __builtin_expect only if __GNUC__
* src/factor-ng.c (LIKELY, UNLIKELY) [__GNUC__]: Add #ifdef guard.
build: avoid warning about unused macro
* src/factor-ng.c (__GMP_DECLSPEC): Don't define here
* src/longlong.h (__GMP_DECLSPEC): Define if not already defined.

* src/factor-ng.c: New file, from nt-factor.
* src/longlong.h: New file.
* NEWS (Improvements): Mention the upcoming improvements.
