Merge branch 'lh/cleanup'
* lh/cleanup: (21 commits) Reset ctx.repo to NULL when the config parser is finished Move cgit_parse_query() from parsing.c to html.c as http_parse_querystring() Move function for configfile parsing into configfile.[ch] Add cache.h Remove global and obsolete cgit_cmd Makefile: copy the QUIET constructs from the Makefile in git.git Move cgit_version from shared.c to cgit.c Makefile: autobuild dependency rules Initial Makefile cleanup Move non-generic functions from shared.c to cgit.c Add ui-shared.h Add separate header-files for each page/view Refactor snapshot support Add command dispatcher Remove obsolete cacheitem parameter to ui-functions Add struct cgit_page to cgit_context Introduce html.h Improve initialization of git directory Move cgit_repo into cgit_context Add all config variables into struct cgit_context ...
