Changed to use simple indexing instead of while (count--) in buf_read()/buf_write(),
because the count overflowed from 0 to max on the last iteration. While the unsigned
integer overflow is defined and behaviour was correct, making this simple change
allowed enabling the sanitizer which might catch true errors elsewhere in the code.

Mainly to clean up the code. Also fixed handling of
PB_LTYPE_FIXED_LENGTH_BYTES for proto3 files.

If the type is string, do not try to deference it as int16, int32 or int64.
This may lead to unalign memory access, which may cause trap on some architectures (ARM)

Need to generate compile time check if the bytes field + size field
might exceed 255 bytes. Also eliminated spurious checks generated
for some callback fields.

Add inline allocation of bytes fields

This commit adds a new FT_INLINE allocation type that forces bytes
fields to be inlined into the struct. E.g., pb_byte_t my_bytes[32].
This requires max_size for the bytes field. The FT_INLINE type is
represented as a new LTYPE: FT_LTYPE_FIXED_LENGTH_BYTES.

This commit also updates the documentation with FT_INLINE and
FT_LTYPE_FIXED_LENGTH_BYTES.

Added an AUTHORS file in apparent order of appearance in the git log
history from $(git log --all).

Add bazel BUILD file for nanopb.

Fix suggested by Ulenspiegel.

Also added testcase for the same.
