5defa985db config.mk: improve feature test macros and compatibility 
- add missing header netinet/in.h for socket declarations (POSIX).
- rename sendfile to responsefile, sendfile(2) is a syscall on FreeBSD.
- remove _XOPEN_SOURCE: this will give a warning about strptime on Linux
  glibc, but unbreaks the build on NetBSD and FreeBSD.

thanks also to josuah and quinq for testing!

075e314bdd Improve vhost handling and fix an uninitialized variable use 
It was not a good thing to depend on the value of i so late in the code
again. If for some reason a loop is added beforehand it would break the
logic.

ecb0d9e54e Do not remove existing socket file 
Check for its presence and bail out if found.
If the socket file is present, either a server is already bound to it,
or the last one errored out and we'd want to inspect this.
Also it could be an unrelated file given by error.

141bb88af1 Cleanup socket file at exit. 
We can't unlink the file if it's outside the chroot, so we need to keep
a simple worker outside of it.

000553d8c5 Add vhost support 
As given in the config, we match a regex of hosts to a canonical host
which points to an internal directory.
Regexes are compiled on initialization, so we can error out early.
The rest is just modifications to use relative directories rather than
absolute ones, as we chdir() into the vhost directories dynamically.

Given we normalize the targets beforehand, there is no danger of
malformed requests escaping the vhost-context.

eda2c150e4 improve byte-range support 
this fixes the lower and upper offset and adds a 416 (range not satisfiable
status). It returns the filesize if it cannot be satisfied as the standard
suggests so the client can do something.

9b8e2bdeb6 byte-range: fix range check for upper limit 
the range check was done after the check lower > upper
so if it meets these conditions: lower <= upper and
lower > st.st_size then lower could still be > upper.
