Version 1.5

Removed these options from libnss-mysql.cfg: timeout, compress, initcmd
libnss-mysql version 1.4

Use argument number in format string
Break query using new line continuation feature

Remove memory.c and directly call malloc/realloc/free
Put MAX_LINE_SIZE back to 1024 for backward compatibility reasons

s/LEN/SIZE
Added MAX_QUERY_SIZE, MAX_NAME_SIZE, MAX_KEY_SIZE, MAX_VAL_SIZE for cleaner
      implementation and support of line continuation
Added DRETURN
Removed free/malloc protos

Moved stdlib.h to nss_mysql.h

Don't waste time memset'ing key/val
Cleanup, comments ...
s/LEN/SIZE
Use new MAX_VAL_SIZE instead of MAX_LINE_SIZE
Don't bother dealing with fopen() errors - validate_config will catch it
Use *foo instead of strlen(foo) to check validity

Moved stdlib.h to nss_mysql.h
Fixed null pointer derefence with safe_memset

Check retval of snprintf()

lsof note

Return false if unhandled sin_family
Don't strlen (query) to check it - unnecessary

due to euid-change detection fix from 1.2

Removed unused variables

Additional debugging and logging

[section]'s are meaningless (and safely ignored) now
All config variables are strings now
Use constant instead of sizeof() in while loop to reduce execution time
Config defaults are used in local routines instead of being set into the
conf structure
No end-user changes required, but deleting [section]'s is recommended
