- Add support for filtering the the list of providers by a regular expression, which makes it possible to only see interesting providers. "f" is used inside gstat to set a filter, "F" is used to remove current filter. - Do not print some uninteresting values in the gstat title line. - Do not print past the end of the screen. - Read multiple keystrokes per "wait" when gstat is running. - Remove a redundant != check, right after check of NULL against the same variable ("gid"). - Use sysexits.h. - Do not link against libkvm and libsbuf, they are not actually used. - Fix a few style(9) issues where I had to touch nearby code anyway.
