transports: smart: fix potential invalid memory dereferences
When we receive a packet of exactly four bytes encoding its
length as those four bytes it can be treated as an empty line.
While it is not really specified how those empty lines should be
treated, we currently ignore them and do not return an error when
trying to parse it but simply advance the data pointer.
Callers invoking `git_pkt_parse_line` are currently not prepared
to handle this case as they do not explicitly check this case.
While they could always reset the passed out-pointer to `NULL`
before calling `git_pkt_parse_line` and determine if the pointer
has been set afterwards, it makes more sense to update
`git_pkt_parse_line` to set the out-pointer to `NULL` itself when
it encounters such an empty packet. Like this it is guaranteed
that there will be no invalid memory references to free'd
pointers.
As such, the issue has been fixed such that `git_pkt_parse_line`
always sets the packet out pointer to `NULL` when an empty packet
has been received and callers check for this condition, skipping
such packets.

Fix #3094 - improve use of portable size_t/ssize_t format specifiers.
The header src/cc-compat.h defines portable format specifiers PRIuZ, PRIdZ, and PRIxZ. The original report highlighted the need to use these specifiers in examples/network/fetch.c. For this commit, I checked all C source and header files not in deps/ and transitioned to the appropriate format specifier where appropriate.

Make our overflow check look more like gcc/clang's
Make our overflow checking look more like gcc and clang's, so that
we can substitute it out with the compiler instrinsics on platforms
that support it. This means dropping the ability to pass `NULL` as
an out parameter.
As a result, the macros also get updated to reflect this as well.

Use `size_t` to hold size of arrays
Use `size_t` to hold the size of arrays to ease overflow checking,
lest we check for overflow of a `size_t` then promptly truncate
by packing the length into a smaller type.

protocol: basic support for multi_ack_detailed
This tells the server that we speak it, but we don't make use of its
extra information to determine if there's a better place to stop
negotiating.
In a somewhat-related change, reorder the capabilities so we ask for
them in the same order as git does.
Also take this opportunity to factor out a fairly-indented portion of
the negotiation logic.
