it can return a pointer to a static location, as described in the manpage.
This can happen on a Linux system with a foreign locale, where the LANG=C messages are
returned this way. (BB #1403)

Fix testcase, INSTREAM should say UNKNOWN COMMAND in old mode and close conn, sending
anything after it will likely result in a broken pipe.(BB #1407)
git-svn: trunk@4826
This means that IDSESSION/INSTREAM must be sent as nIDSESSION\n or zIDSESSION\0,
ditto for INSTREAM.
Adjust testcases accordingly.
Old commands are still accepted when sent without delimiter.
git-svn: trunk@4811
since a buggy client implementation may get stuck in send(), and then clamd
gets stuck in send() -> deadlock. To avoid this we need nonblocking sockets, and
(low) timeouts on send.
Add more tests for clamd protocol, including a stress test for IDSESSION.
git-svn: trunk@4798
Make handling of old-style commands compatible with old clamd: if they have a \n
that will delimit the command.
If multiscan of a single file encounters errors, don't reply OK too.
git-svn: trunk@4796
handle multiple %v parameters
introduce poll_fds that also does the read into a buffer
introduce thrmgr_group* commands for keeping track of groups of commands
(multiscan, IDSESSION)
introduce 2 queues in thrmgr, multiscan queues get lower priority. Commands
are processed from both queues in a 4:1 ratio to avoid starvation.
unify reply code: conn_reply*
unify scanner code into scan_callback that is called from cli_ftw
multiscan doesn't need stat() now if readdir() provides dt_type
redesign clamd main loop: there is now an accept thread, and a
recv()/dispatch thread, +MaxThreads worker (scanner) threads.
introduce limiting on commands when worker threads are contended.
introduce IDSESSION, a replacement for the old SESSION command, that allows
asyncronous (scan) commands and scan replies
introduce INSTREAM that allows sending the data to scan on same connection
(vs STREAM that requires another port)
introduce zCOMMANDS
git-svn: trunk@4755
poll()/select() from another thread.
It introduces subtle bugs.

Also introduce MaxQueue, this will prevent clamdscan from flooding
clamd with too many FILDES requests.

Though when poll says that socket is closed, we shouldn't try closing again
if we're in WAIT_REPLY mode (since we alraedy closed it from another thread).
