(mark) to indicate whether to mark all found hashes (or stop on first found).

mark found hashes and only write the not-found hashes to disk, rather than not
writing *any* hashes (when any match) because the message is a "dupe".
When update is false, the behavior is the same as before.

(using smb_close_fp).

Created smb_hashstr() to create hashes of ASCIIZ data.

Don't set binary _fmode for Win32 (we want carriage returns in the log file).

hash values are found in the smb.hash file (new feature).
Prints note about using 'fixsmb' to repair/update message bases upon error(s).

New smb.hash file uses multiple hashing methods (CRC-16, CRC-32 and MD5) to
calculate hashes of various "distinguishing marks" (e.g. message ID and body
text) to create a permanent history of message "fingerprints" that can be used
for duplicate message detection or fast location of messages based on one
of these "distinguishing marks". For example, reading each message header
in a message base to find a message with a specific message-ID (i.e.
how get_msg_by_id() currently works) significantly slows down message
importing with auto-thread linkage (a newly added feature). This hash file
will be used to speed this up considerably as well as improve duplicate
message detection.

This feature is supported with the following new smblib functions:
smb_findhash, smb_hashmsg, smb_hash, smb_msghashes, and smb_addhashes.

smb_addmsghdr() currently calls smb_hashmsg(), but this will probably change
with yet another new function call (smb_addmsg?) which will have access to the
body text (a very useful hash for duplicate message detection).

Existing SMB message bases will not have an existing .hash file (chksmb will
"missing hash" errors), but fixsmb can be used to create the .hash file for
existing message bases. Other than the chksmb errors, there are no real
problems with missing hashes, accept for the potential for failed auto-thread
linkage when importing replies to existing messages. Over time, this will fix
itself as new messages are imported and their hashes are stored automatically.

Projects using smblib now must link with crc16.c, crc32.c, and md5.c.

Other changes:
Created GETMSGTXT_TAIL_ONLY convenience macro.
smb_open/close_ha/da functions are now just macros to the new smb_open_fp and
smb_close_fp functions. These functions were 99% redundant.
New macros smb_open/close_hash also point to smb_open/close_fp.
More use of SAFEPRINTF macros and safe_snprintf().

FREE_AND_NULL, FREE_LIST, and FREE_LIST_ITEMS.
