Import combinator and allocator APIs into SWIG. Next is glue. Need to fix unions in HParsedToken and HCaseResult.

 * "in_" and "not_in" should coerce their results to strings (i.e., chr(result))
 * TestLeftrec: success case 2 fails
 * TestChRange: success case segfaults
 * TestWhitespaceEnd: success case segfaults
 * TestAction: success case segfaults with "corrupted double-linked list"
 * TestButNotRange: segfaults, probably because of whatever's wrong with ch_range
 * TestXor: segfaults; failure case craps out with "malloc(): smallbin double linked list corrupted"

Add void* userdata to callbacks

Allow in-place build via scons --in-place

Make install_name darwin-only

Changes for doing a proper system install and Go bindings

Specify warning for internal only headers that are now installed for use
by extensions.

Reduce IRC spam

This actually is only for OS X. On linux ldconfig must be run after
installing in order to update the library cache. Need to look into how
to get scons to do this for the user.

Set the proper path for the shared library so that anything linking
against it will be able to find the library.

Go, and likely other language bindings will, need access to create
new combinators. This functionality is currently located
src/parsers/parser_internal.h. Install this header to the system with
dependent headers until a better solution can be found.

Clean up pyc

Generate pkg-config for Hammer

Create a pkg-config file and install it to $prefix/lib/pkgconfig

Added token type registry. Closes #45; see also #54

Static analysis

h_sequence need PB_MIN set.

Add internal conditional to not use stdarg.h for SWIG use

Ditch longs and long longs in favor of stdint.h types, which has cascadi...

effects throughout, including use of inttypes.h/PRI[ud]64 because printf() is
still stuck in a long world, conversion of %lu to %zu for printing values of
type size_t, and changing/renaming the g_check_cmp* family of functions.

Fix SCons bugs

Don't pass the entire environment to SCons. Only pass the PATH

Don't clober the Environment (and thus the ENV['PATH'] by redefining it
and don't link against lr by default. Only add it if uname is not Darwin
