*) 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.
