226be952e7 Fix gstat's interactive f and q commands
curses and libedit don't play well together. After last year's libedit
upgrade in head, they play even less well together. This change resets some
curses settings after they get screwed up by libedit calls. Without it,
gstat's interactive commands require an extra "enter", screw up the terminal
on exit, and screw up the display if the user enters an invalid filter
string.

85e8cd9339 Use strlcpy() in favor of strncpy() as it's defined to have a nul character
at the end of string buffer, and the code context do expects this to behave
correctly (e.g. strchr).

Note that we do not believe there is real-world impact for gstat(8)'s usage
because the strings are length checked, and the on-stack buffer belongs to
main() and we can expect to have zeros in them.

9381337d5a Add an option, -p, which makes gstat(8) to only display physical providers
(those with rank of 1).

3485cea7b7 - Allow gstat to print values to different kind of outputs.
- Introduce batch mode, where gstat will collect the numbers, print them, and
  exit.
- Document batch mode in the gstat man page.

78269e8b8c When the ms/req fields exceed 1 second, drop the fractions to fit more digits.
This is unfortunately necessary with some flash based devices which can
get hundreds of seconds behind with softupdates enabled.

f767e585af - 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.

GCC doesn't warn about them without -pedantic.

01eed200f9 Make libgeom usable by C++ programs:
- Add DECL wrappers to libgeom.h.
- Rename structure members in libgeom.h to use a lg_ prefix for member
  names.  This is required because a few structures had members named
  'class' which made g++ very unhappy.
- Catch gstat(8) and gconcat(8) up to these API changes.
