nginx-0.1.2-RELEASE import

*) Feature: the --user=USER, --group=GROUP, and --with-ld-opt=OPTIONS
       options in configure.

    *) Feature: the server_name directive supports *.domain.tld.

    *) Bugfix: the portability improvements.

    *) Bugfix: if configuration file was set in command line, the
       reconfiguration was impossible; the bug had appeared in 0.1.1.

    *) Bugfix: proxy module may get caught in an endless loop when sendfile
       is not used.

    *) Bugfix: with sendfile the response was not recoded according to the
       charset module directives; the bug had appeared in 0.1.1.

    *) Bugfix: very seldom bug in the kqueue processing.

    *) Bugfix: the gzip module compressed the proxied responses that was
       already compressed.
