Prefer plain 'static' to 'static inline'.

Prefer plain 'static' to 'static inline'.

I missed these instances of 'static inline' in an earlier sweep.
* ebrowse.c (putstr):
* etags.c (hash):
* make-docfile.c (put_char): No longer inline.
* etags.c (hash): Prefer int to unsigned when either will do.
