I don't think we've discussed this API enough.

««« original CL description
bike/shed: new package.

It comes up often enough that it's time to provide
the utility of a standard package.

Still TODO: parsing optimizations

make_perl_groups.pl is copied with minimal modifications
(just to generate Go syntax instead of C++) from RE2.
Google Inc is "The RE2 Author" of that file and is one of
the Go Authors, so copyright changed to the Go Authors instead.

The "elf.h" header changes involve only comments, the released
Plan 9 C preprocessing function does not cope with multiline
comments following the #define keyword.  All multiline comments
have been moved to the line above the associated definition.
Sigh!  Fixing the Plan 9 compiler is not an option.

<time.h> does not exist in the Plan 9 Native library.  I have
moved it from src/cmd/ld/pe.h to include/u.h. RSC correctly points
out that this copy of <u.h> is not the one used to compile the
Go release on Plan 9 platforms.

The ptrace syscall remains gutted on darwin, but usable.  This
also makes the syscall addition process reproducible on darwin
instead of relying on a file path in rsc's home directory.
I've also removed an override of $PATH in env.bash that made
tooling harder.

If we fail due to a missing command (always bison)
during the build, it is running many things in parallel
and the error message gets lost in the noise.
Also diagnose bison++.

$ ./make.bash
Your system's bison is bison++, a buggy copy of the original bison.
Go needs the original bison instead.
See http://golang.org/doc/install.html#ctools
$ sudo apt-get remove bison++
... ridiculous amount of output ...
$ ./make.bash
Cannot find 'bison' on search path.
See http://golang.org/doc/install.html#ctools
$ sudo apt-get install bison
... ridiculous amount of output ...
$ ./make.bash
... works

Parser is a work in progress but can populate most of the
interesting parts of the data structure, so a good checkpoint.
All the complicated Perl syntax is missing, as are various
important optimizations made during parsing to the
syntax tree.

The plan is that exp/regexp's API will mimic regexp,
and exp/regexp/syntax provides the parser directly
for programs that need it (and for implementing exp/regexp).

Once finished, exp/regexp will replace regexp.
