Also, revert my earlier change to move installation path mashing from
Makefile.global to configure.  Turns out not to work well because configure
script is working with unexpanded variables, and so fails to match in
cases where it should match.

all the code that looks for other binaries.  I move FindExec into
port/exec.c (and renamed it to find_my_binary()).  I also added
find_other_binary that looks for another binary in the same directory as
the calling program, and checks the version string.

The only behavior change was that initdb and pg_dump would look in the
hard-coded bindir directory if it can't find the requested binary in the
same directory as the caller.  The new code throws an error.  The old
behavior seemed too error prone for version mismatches.

conversion of basic ASCII letters.  Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower.  These functions use the same notions of
case folding already developed for identifier case conversion.  I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent.  Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.

our job easier for porting.
