pgindent run.

Replace regular expression package with Henry Spencer's latest version
(extracted from Tcl 8.4.1 release, as Henry still hasn't got round to
making it a separate library).  This solves a performance problem for
multibyte, as well as upgrading our regexp support to match recent Tcl
and nearly match recent Perl.

Remove sys/types.h in files that include postgres.h, and hence c.h,
because c.h has sys/types.h.

Remove #ifdef MULTIBYTE per hackers list discussion.

Implement SQL99 OVERLAY(). Allows substitution of a substring in a string.
Implement SQL99 SIMILAR TO as a synonym for our existing operator "~".
Implement SQL99 regular expression SUBSTRING(string FROM pat FOR escape).
 Extend the definition to make the FOR clause optional.
 Define textregexsubstr() to actually implement this feature.
Update the regression test to include these new string features.
 All tests pass.
Rename the regular expression support routines from "pg95_xxx" to "pg_xxx".
Define CREATE CHARACTER SET in the parser per SQL99. No implementation yet.

Clean up portability problems in regexp package: change all routine
definitions from K&R to ANSI C style, and fix broken assumption that
int and long are the same datatype.  This repairs problems observed
on Alpha with regexps having between 32 and 63 states.

Removed MBFLAGS from makefiles since it's now done in include/config.h.

Change #include's to use <> and "" as appropriate.

OK, folks, here is the pgindent output.

Add auto-size to screen to \d? commands.  Use UNION to show all
\d? results in one query. Add \d? field search feature.  Rename MB
to MULTIBYTE.

From: t-ishii@sra.co.jp

Included are patches intended for allowing PostgreSQL to handle
multi-byte charachter sets such as EUC(Extende Unix Code), Unicode and
Mule internal code. With the MB patch you can use multi-byte character
sets in regexp and LIKE. The encoding system chosen is determined at
the compile time.

To enable the MB extension, you need to define a variable "MB" in
Makefile.global or in Makefile.custom. For further information please
take a look at README.mb under doc directory.

(Note that unlike "jp patch" I do not use modified GNU regexp any
more. I changed Henry Spencer's regexp coming with PostgreSQL.)

Goodbye register keyword.  Compiler knows better.

Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.

Massive commit to run PGINDENT on all *.c and *.h files.

Various patches from Bryan that *should* clean up the compile problems
ppl are seeing with v2.0

Moved the include files to src/include/regex
