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
