2b6b300f91 Custom printers for user token types 
I did this in a hurry, but it appears to work locally. I tested it with
a couple boring custom token type printers.

3fc56a0dc3 add h_alloc() which calls errx() on failure and use it for all basic allocation 
Rationale: "Basic allocation" refers to things outside of parsing proper,
mostly initialization. If such allocations fail, the system is globally
emory-starved from which it will likely not recover by returning failure.
In this case, terminating the process is in fact the most robust strategy as
it may mean the difference between a permanent hang and a temporary crash.

0c35525e30 Convert usages of errx to h_platform_errx 
This BSD call will have to be implemented on windows. Right now
we have a stub that just exits the process.

af73181cf4 Fix #118 
NEWS:
* Switching endianness mid-byte no longer potentially re-reads bytes.
* bit_offset now consistently refers to the number of bits already
  read.
* HParsedTokens now have a bit_length field; this is a size_t.  This
  may be removed for memory reasons.

The bit writer has not yet been updated to match; the result of
switching bit writer endianness in the middle of a byte remains
undefined.

c8fc061ea6 Ditch longs and long longs in favor of stdint.h types, which has cascading 
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.
