PA_ADD_LANGFLAGS() was broken, resulting in among other things
--enable-lto not working.

Things used by "make dist" haven't been updated for a while, it seems;
in particular have not kept up with the existence of autogen.sh.

Not all versions of sed has "sed -r", so change it to use basic
regular expressions. Furthermore, not all systems support \| in basic
regular expressions, to work around it by converting the script names
explicitly.

config/unconfig.h really is no different than the other perlreq files,
so move it into the Makefile. This has the extra advantage that
config/unconfig.h no longer needs to be kept in the source repository.

config/config.h as generated by autoconf has #undef directives
commented out, but the autoheader-generated template contains them,
and config/unconfig.h should not contain them. Re-introduce
config/config.h.in, and postprocess it to generate config/unconfig.h
by commenting out all the #undef directives, just as configure does.

Updating the autoconf helpers unconditionally is very noisy and
probably the wrong thing to do anyway. Check the version numbers and
only update if the current machine has a newer version installed.

Allow overriding the autotools install location via environment
variables.
Handle missing aclocal or automake, which aren't mandatory as we cache
the files we get from them.

The name "aux" is reserved on Windows platforms, a legacy from CP/M
via MS-DOS. Rename it to "helpers".
Turns out that that directory wasn't actually used properly, because
AC_CONFIG_AUX_DIR was never defined, and there was a redundant copy of
install-sh checked into the base of the source tree.

Make further autoconf rule improvements and update the required
version of autoconf to 2.69. That version is now 5+ years old and
although there might be older versions which have the prerequisite
macros they are known to have lots of bugs, and we can't really test
them.

Instead of trying to do hacks in the Makefiles, define header files
for specific compilers if they can't use autoconf. Currently defined
for Microsoft Visual Studio, based on MSDN documentation. It is
currently untested.

It's become custom to create a script called autogen.sh, which creates
all the auto-generated files using all the appropriate auto* tools when
run, so one doesn't have to worry about checking them into the repository.
This seems like a good idea, follow suit.
