fix ge build

less logger.h

make ge work again

remove now unused ibuf variable

rework the daemon to do fork+exec It uses the 'common' proc.c from various OpenBSD-daemons. gmid grew organically bit by bit and it was also the first place where I tried to implement privsep. It wasn't done very well, in fact the parent process (that retains root privileges) just fork()s a generation of servers, all sharing *exactly* the same address space. No good! Now, we fork() and re-exec() ourselves, so that each process has a fresh address space. Some features (require client ca for example) are temporarly disabled, will be fixed in subsequent commits. The "ge" program is also temporarly disabled as it needs tweaks to do privsep too.

use fatal() in code used in the daemon

switch to the more usual log.c

rename log.[ch] to logger.[ch]

nitpick: fix snprintf check

move config-related code to config.c reuse it in ge too.

call setlocale()

move and dedup the tls initalization in server.c

provide a more usual fatal fatal usually appends the error string. Add 'fatalx' that doesn't. Fix callers and move the prototypes to log.h

move some server-related code to server.c

make the various strings in the config fixed-length will help in future restructuring to have fixed-size objects.
