mdocml: Use __attribute__((__format__ throughout.

mdocml: Use __attribute__((__format__ throughout.

[schwarze]

Log Message:
-----------
Use __attribute__((__format__ throughout.
Triggered by a smaller patch from Christos Zoulas.

While here, unify style, move several config tests to config.h,
and delete the useless MANDOC_CONFIG_H.
