add_mime nows allocate dinamically copies of the passed strings, so that we can actually free what we parse from the config file. This matters a lot especially with lengthy `types' block: strings that reach the internal mapping are never free'd, so every manual addition is leaked.

matches found with % grep -R '=[ ]*{' . | fgrep -v const

The `map' rule is powerful but quite annoying to use if you have/need lots of entries (and clutters the configuration file too.) The `type' block is blatantly stolen from httpd(8) and allows for a way more nice usage: type { include "/usr/share/misc/mime.types" } or even type { text/markdown md markdown text/x-perl pl pm # ... }

add a `sni' option for the `proxy' block: the given name is used instead of the one extracted by the `relay-to' rule.

refactor the code that calls validate_against_ca into an helper function to reuse it in both apply_require_ca and (optionally) in apply_reverse_proxy.

as a side effect the order of the content of a server block is relaxed: options, location or proxy blocks can be put in any order.

I forgot to free some strings when they're no more used.
