remove the dummy typedef for struct SoupSessionFeature that was needed
* libsoup/soup-session-feature.h: remove the dummy typedef for
struct SoupSessionFeature that was needed because we weren't
scanning soup-types.h. Fixes the build with non-GNU compilers.
* libsoup/soup-session-feature.c: document
SoupSessionFeatureInterface
* docs/reference/Makefile.am (IGNORE_HFILES): oops, don't ignore
soup-types.h
* docs/reference/libsoup-2.4-docs.sgml:
* docs/reference/libsoup-2.4-sections.txt: Split
SoupSessionFeature into its own file.
