CVS log for: hand.c

Keep-alive actually works now.  Major request parsing cleanup.

Lots of changes:
 * Use either buffering code taken from Apache or TCP_CORK to minimize
   network traffic.
 * Sockets are now properly 'half-closed' before being truly closed
 * Make 503 responses a compile time option
 * Make HTTP PUT a compile time option
 * Added -b command line switch to change server's accept backlog
 * Lots of code cleanup
 * More statistics kept for verbose (-v) output

- fixed critical bug that caused only the first part (probably about 256K)
  of a file to actually be returned to the user
- CoW was using a pool of pmsg structures for communication between the
  main thread and the depot, but was malloc'ing messages sent from the
  depot to the handlers; messages are now forwarded to handlers instead of
  copied so we avoid the malloc overhead
- CoW now re-uses server socket so we don't have to wait a couple minutes
  after shutdown before restarting (avoids "Address in use" messages)

- added config option to disable TCP Nagle algorithm
- made request.c more lenient in terms of input; also heavily
  cleaned up/commented code

Added configuration file support.  Also updated the build system some more.
Although the config file support is in place, not all of its options are
completely supported yet.

Fixed major depot loop bug that caused CoW to crash on the first request.
Also added lots of comments to the depot and made some more reformatting
changes.

Indentation changes and minor build fix.

Changed indentation style.

Initial import of Takashi's CoW code (version 0.3.2).
