384e686fe6 Do not generate has_ fields for callback fields. 
The arg field can be used to store the field presence from inside
the callback. Furthermore, having the has_ field for encoding callbacks
would be more annoying than useful.

214b0eae8a Change the callback function to use void**. 
NOTE: This change breaks backwards-compatibility by default.
If you have old callback functions, you can define PB_OLD_CALLBACK_STYLE
to retain the old behaviour.

If you want to convert your old callbacks to new signature, you need
to do the following:

1) Change decode callback argument to   void **arg
      and encode callback argument to   void * const *arg.

2) Change any reference to arg into *arg.

The rationale for making the new behaviour the default is that it
simplifies the common case of "allocate some memory in decode callback".

03e5393072 Add PB_SYSTEM_HEADER compile time option. 
This allows replacing the C99 standard include file names with
a single system-specific file. It should provide all the necessary
system functions (typedefs, memset, memcpy, strlen).

69085d9387 Rename PB_HTYPE_ARRAY -> PB_HTYPE_REPEATED. 
This is a more logical name in parallel with PB_HTYPE_REQUIRED and PB_HTYPE_OPTIONAL.

You will have to regenerate the files and recompile.

258ba8335d Reformat generated .pb.c files using macros.

2) Simpler generator logic
3) Tidier looking, easier to read .pb.c files

39b8a5e2bb Make pb_decode_varint32 a separate implementation. 
This avoids doing 64-bit arithmetic for 32-bit varint decodings.
It does increase the code size somewhat.

Results for ARM Cortex-M3: -10% execution time, +1% code size, -2% ram usage.

c372ebc665 Performance improvement: replace memcpy with loop. 
In the pb_istream_from_buffer and pb_ostream_from_buffer, memcpy was
used to transfer values to the buffer. For the common case of
count = 1-10 bytes, a simple loop is faster.
