The [] characters are used for quoting in m4, so the attempt to use
them in place of `test` fails yielding the warning at build time:
.../flex/configure: line 20222: no: command not found

This is taken from OpenSSH Portable, which in turn takes it from
OpenBSD.
reallocarray wraps the stdlib's realloc function. It takes two size
arguments and checks for overflow, like calloc, but doesn't zero the
memory. Therefore, it allows us to do overflow-safe array reallocations
and overflow-safe unzeroed array allocations, which the stdlib
allocation functions don't.
We have a bunch of specific array allocation macros, none of
which check for overflow. reallocarray should be able to replace them.

Added test for presence of (g)texi2dvi program. Gave notice if texi2dvi
is unavailable and set TEXI2DVI=: to avoid giving users headaches.
Enhanced tests for bison and help2man with notices when the programs
aren't found. Set their program variables to use the missing script
in build-aux since it's compatible with them.

In an effort to reduce top level directory clutter, reintroduced the
call to AC_CONFIG_AUX_DIR. Moved the call to LT_INIT to after that
call so configure will be able to find its files.

Unfortunately, automake 1.14.1 does not play nicely with
AC_CONFIG_AUX_DIR, so upgrading the used automake version required
removing the build-aux directory and letting autoconf's installed
helper files live more over the tree.

Since tools/git2cl is a dependency of ChangeLog, not distributing
tools/git2cl with flex causes the "make dist" target to fail in the distributed tar ball.

The *.[chly] sources are now in the src directory. This implies a
bunch of changes in Makefile.am and friends to account for the new
location. The .gitignore files are now more local to places where various object files and generated source files occur.

Since it is not possible to rebuild the ChangeLog file without being
in a git working directory of flex, distributing the tools directory is misleading. In particular, git2cl will always fail.

Autoconf had trouble finding the shared libraries for gettext. Using
gettext 0.18 fixes that.
When updating the gettext version number, autoreconf could fail to
update files, since autopoint would assume the gettext-related files had
been locally modified. Passing --force prevents that from happening.
