[PATCH 12/19] gitweb: Parse two-line from-file/to-file diff header in git_patchset_body

Parse two-line from-file/to-file unified diff header in git_patchset_body directly, instead of leaving pretty-printing to format_diff_line function. Hashes as from-file/to-file are replaced by proper from-file and to-file names (from $diffinfo); in the future we can put hyperlinks there. This makes possible to do blobdiff with only blobs hashes.

The lines in two-line unified diff header have now class "from_file" and "to_file"; the style is chosen to match previous output (classes "rem" and "add" because of '-' and '+' as first character of patch line).
