16e55c6262 Change meaning of root (backwards incompatible!) 
This takes the nginx approach to the "root" directive, which is simpler
to implement and more consistent with more complex routing behaviors
like regexp.

The path component of the URL is now simply appended to the root to form
the path to the file which should be served to the client.

7e8a953794 Initial pass on regex routing support 
All this does is parse the regexes out of the config file.

I've vendored libregexp from Bellard's quickjs project, because it's
reasonably small and self-contained, and POSIX regexes don't support
captures. We're eventually going to want captures for URL rewrites, so
this'll do for now.

a22bec5149 add a missing "/" to autoindex paths 
With the following directory structure:

/srv/gmni:
baz/  foo/

/srv/gmni/baz:
a

/srv/gmni/foo:
bar/

/srv/gmni/foo/bar:
b

trying to access gemini://somesite/ with autoindex=on works,
but accessing /foo fails because it tries to stat /srv/gmni/foobar
instead of /srv/gmni/foo/bar. This commit fixes that by adding a trailing slash.

9d17ce46b0 return false on request_validate errors 
This will report proper errors to clients rather than continuing on with
request processing.

7fed84898b Only handle one client per poll iteration 
This is a bit of a hack but it avoids some problems with invalid reads
when a client gets disconnected
