[PATCH v2 00/22] HTTP status code improvements

[John Keeping]

Changes since v1 (starts at [0]):
- Rebased on the latest master
- Following Christian's patch [1], a new patch changes ui-patch.c to use
  cgit_print_error_page() and other new patches fix similar issues in
  ui-blob.c and ui-snapshot.c
- The last patch is new, and uses "cache-dynamic-ttl" for error pages;
  I'm not 100% sure about that, but it's better than the current
  behaviour if someone tries to access a page by SHA1 before the object
  has been pushed to the repository CGit is displaying
