/bin/bash is not available on every system, nor always the default.
/bin/sh is standardised, but not always the preferred interactive shell,
hence it's configurable.

There's no need to check for the existence of this shell during config,
since it's an option that only affects run-time - and you may compile
ncdu on a totally different system than you would run it on.

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.
