/*
* This is the structure that the builders impose on the private data
* that is pointed to by the bldr_private pointer in each header entry.
*
* The bldr_private pointer points to a PrivateTop which consists of two
* parts, whose purposes are independent:
* ******* This part no longer exists ******
* encoded -- This is used to preserve the charset information for
* addresses in this entry. For example, if the user types
* in a nickname which has a charset in it, the encoded
* version containing the charset information is saved here
* along with a checksum of the text that created it (the
* line containing the nickname).
* etext -- Pointer to the encoded text.
* chksumlen -- Length of string that produced the etext.
* chksumval -- Checksum of that string.
* The string that produced the etext is just the displayed
* value of the entry, not the nickname before it was expanded.
* That's so we can check on the next builder call to see if it
* was changed or not. Appending or prepending more addresses to
* what's there will work, the etext from the old contents will
* be combined with the etext from the appended stuff. (The check
* is for appending or prepending so appending AND prepending all
* at once won't work, charset will be lost.) If the middle of the
* text is edited the charset is lost. If text is removed, the
* charset is lost.
*
* affector -- This is for entries which affect the contents of other
* fields. For example, the Lcc field affects what goes in
* the To and Fcc fields, and the To field affects what goes
* in the Fcc field.
* who -- Who caused this field to be set last.
* chksumlen -- Length of string in the "who" field that caused the effect.
* chksumval -- Checksum of that string.
* The string that is being checksummed is the one that is displayed
* in the field doing the affecting. So, for the affector in the
* Fcc headerentry, the who might point to either To or Lcc and
* then the checksummed string would be either the To or Lcc displayed
* string. The purpose of the affector is to remember that the
* affected field was set from an address book entry that is no
* longer identifiable once it is expanded. For example, if a list
* is entered into the Lcc field, then the To field gets the list
* fullname and the fcc field gets the fcc entry for the list. If
* we move out of the Lcc field and back in and call the builder
* again, the list has been expanded and we can't tell (except for
* the affector) that the same list is what caused the results.
* Same for the To field. A nickname entered there will cause the
* fcc of that nickname to go in the Fcc field and the affector
* will cause it to stick as long as the To field is only appended to.
*
* It may seem a little strange that the PrivateAffector doesn't have a text
* field. The reason is that the text is actually displayed in that field
* and so is contained in the entry itself, unlike the PrivateEncoded
* which has etext which is not displayed and is only used when we go to
* send the mail.
