str: introduce `git_str` for internal, `git_buf` is external
libgit2 has two distinct requirements that were previously solved by
`git_buf`. We require:
1. A general purpose string class that provides a number of utility APIs
for manipulating data (eg, concatenating, truncating, etc).
2. A structure that we can use to return strings to callers that they
can take ownership of.
By using a single class (`git_buf`) for both of these purposes, we have
confused the API to the point that refactorings are difficult and
reasoning about correctness is also difficult.
Move the utility class `git_buf` to be called `git_str`: this represents
its general purpose, as an internal string buffer class. The name also
is an homage to Junio Hamano ("gitstr").
The public API remains `git_buf`, and has a much smaller footprint. It
is generally only used as an "out" param with strict requirements that
follow the documentation. (Exceptions exist for some legacy APIs to
avoid breaking callers unnecessarily.)
Utility functions exist to convert a user-specified `git_buf` to a
`git_str` so that we can call internal functions, then converting it
back again.

buf: remove internal `git_buf_text` namespace
The `git_buf_text` namespace is unnecessary and strange. Remove it,
just keep the functions prefixed with `git_buf`.

tests: address two null argument instances
Handle two null argument cases that occur in the unit tests.
One is in library code, the other is in test code.
Detected by running unit tests with undefined behavior sanitizer:
```bash
# build
mkdir build && cd build
cmake -DBUILD_CLAR=ON -DCMAKE_C_FLAGS="-fsanitize=address \
-fsanitize=undefined -fstack-usage -static-libasan" ..
cmake --build .
# run with asan
ASAN_OPTIONS="allocator_may_return_null=1" ./libgit2_clar
...
............../libgit2/src/apply.c:316:3: runtime error: null pointer \
passed as argument 1, which is declared to never be null
...................../libgit2/tests/apply/fromfile.c:46:3: runtime \
error: null pointer passed as argument 1, which is declared to never be null

apply: test postimages that grow/shrink original
Test with some postimages that actually grow/shrink from the
original, adding new lines or removing them. (Also do so without
context to ensure that we can add/remove from a non-zero part of
the line vector.)

patch: abstract patches into diff'ed and parsed
Patches can now come from a variety of sources - either internally
generated (from diffing two commits) or as the results of parsing
some external data.
