Key 'b' in the browse window spawns a shell in the current directoy.

We first check the $SHELL environment variable of the user for the preferred
shell interpreter. If it's not set, we fall back to the compile time
configured default shell (usually /bin/bash).

Slightly modified patch from Gianluigi Tiesi.

Ncurses provides a pkg-config module which could be used here. If not
available we fall back to the old detection heuristic.

As recent autoconf wants

There's no need to check -lncursesw twice, for example.

POSIX defines ino_t to be of an unsigned integer type, and searching
around the net didn't tell me of any definitions conflicting that. So
every ino_t can be represented in an uint64_t. (Assuming that is the
largest integer type in use for an inode number, but I'm sure that
assumption will hold for a while)

(dev_t, on the other hand, is a bit messier. Still figuring out what to
do with that.)

*Should* be equivalent, but having a clearly standardised width is much
better.

A more modern and practical structure.

I'm now following the same idea from ncdc of using $VERSION+g in the git
repositories.

This (in combination with linking to ncursesw) fixes the display of
non-ASCII characters.

Or force the use of a library with --with-ncurses or --with-ncursesw.
Implementation based on/stolen from the configure.ac in ncmpc.

Removed some obsolete macros and added a few more headers and function
checks.
