Accept sockets are non-blocking, to avoid races where the client closes
before we get to accept it.  (Spotted by: "chen xiaoyong")

Unfortunately, that means that session sockets inherit non-blocking mode,
which is the opposite of what we want in the worker thread but correct
for the acceptor thread.

We prefer to have the extra syscalls in the worker thread, that complicates
things a little bit.

Use ioctl(FIONBIO) instead of fcntl(2) which is surprisingly expensive.

Implement an upper limit for allocated memory, specify as:
	-smalloc,40M

Give the malloc allocator its own stats counters so we can see deeply
into what it does.

(IOV_MAX < (HTTP_HDR_MAX * 2)) is equivalent to (IOV_MAX < (0 * 2)),
which obviously is never true.  Fixes #222.

possible for various modules to add cli functions so they can
be manipulated on the fly.

CLI_AddFuncs() registers a set of CLI functions.  We operate
with three lists: the ones not shown in "help" because the
manager already showed them, the normal ones and the debug
commands which are also not shown in a plain "help".

Move the registration of cli functions out to the code they
belong in: VCL, BAN and VCA.

Give VCA a real Init function, and have the cli function ("start")
initiate the acceptor thread which listens for incoming connections.

Split CLI_Init() into CLI_Init() and CLI_Run()

not have to grope around in the cacher's data structures.

Whenever the manager gets a CLI command it does not understand, it
will pass it to the cacher process, if it is running.

This complicated "help" a little bit, because we want to show the
combined commands of the manager and cacher.

Since we're dealing with help anyway, hide undocumented debug
commands from it.

else (CLI Ping for instance).  This makes it hard to process logs with

change the character used for non-backend-or-client log entries to '-'.
