This makes __free_unpacked() consistent with free(), and simplifies
callers by allowing them to indiscriminately free message objects
without regard to whether they have been allocated or not.
Fix a few casts where ints were cast to uints unnecessarily
Fixes#199. Previously, enums were treated as uint32's, but they need to
be treated as int32's instead.
t: Add a few test cases with negative enum values
warning: assigning to 'uint8_t *' (aka 'unsigned char *')
from 'char *' converts between pointers to integer types
with different sign [-Wpointer-sign]
added check that repeated fields vectors are not NULL
fixed repeated field quantity type: it's "size_t", not "unsigned"
cleaner code, no cast porn
all covered with tests
i'm confused as to why these fields exist, since the typical
implementation of a "temporary alloc" would be something like alloca(),
and alloca() is usually just inlined code that adjusts the stack
pointer, which is not a function whose address could be taken.
this breaks the API/ABI and will require a note in the ChangeLog.
possibly we could revisit the idea of "temporary allocations" by using
C99 variable length arrays. this would have the advantage of being
standardized, unlike alloca().
of the same field on the wire (Fixes#91)
