Log Message:
Bug(s) fixed: 186280
Bug Description: adminserver: Close potential security vulnerabilities 
in CGI code
Reviewed by: Rob, Pete, Nathan, Noriko (Thanks!)
Fix Description: Most of this just involves making sure that we use 
PR_snprintf/PL_strncpyz/PL_strcatn where able, or just making sure we 
use snprintf/strncpy/strncat correctly and null terminate the buffers.  
I also got rid of some dead code, unused variables, and the like.  There 
are a few cases that are more complex that I have specified below.  In 
some cases I had to change the function signature to add a size 
parameter in cases where the function was copying to a given char * and 
the size was assumed (in most cases this was safe but it's still dangerous).
Platforms tested: Fedora Core 5
Flag Day: no
Doc impact: no
