and_nss_mysql_count_tokens().

Split #define's up for readability/flexibility.
Run arg passed (username/uid/etc.) through MySQL's string cleanser;
AS A RESULT ALL STRING FORMATS IN YOUR CONFIG MUST BE %s !!!

Added _nss_mysql_escape_string().

Woops, let's select the spnam fields for real!

changes).
Stop using mysql_ping - it's slow

Changed: DEF_DFLAGS (now 0)
moved MySQL routines to mysql.c

Use contants in a few appropriate areas

can be defined, not multiple servers & queries; keeps things simpler

Better method of saving to BUFFER
Use generic memory alloc routines (which do their own logging)

*ent routines don't need PADSIZE additional bytes
Use static storage for debug/log string

  share the same state information (unlike before).  So it's possible
  for poor code to step on it's own *ent routines; I found the glibc
  library uses the same state information for all functions, so I felt
  comfortable with this move.  I may be proven wrong though ...
Added a few functions so above state information can be accessed/set
  outside this source file.
set ERANGE outside of find_eol
Assume that buffer and structure are not NULL (nss_mysql.c now ensures this)
CLOSE_ALL -> CLOSE_LINK; CLOSE_LINK now also CLOSE_RESULT's
Removed unnecessary \n's on debug lines
Check/set return types using enumerated constants instead of 0's and 1's ...
_nss_mysql_log_error changed to _nss_mysql_log with prio arg
removed debug - it's now in nss_mysql.c

Removed unused FSIZ macro
Removed unused D_ERROR; renumbered D_* defines
Removed unnecessary CLOSE_ALL.  CLOSE_LINK must CLOSE_RESULT anyway
Removed unnecessary \n's on debug lines
Added #defines for some configuration defaults
Lots of new comments
Added boolean and return types so we check/set returns via enumurated
    constants instead of 0's and 1's ...
Added debug_flags to conf.global
Rearranged some stuff for better readability
