Adapt the name of the `strbuf` block source to no longer relate to this
interface, but instead to the `reftable_buf` interface.

Convert the reftable library to use the `reftable_buf` interface instead
of the `strbuf` interface. This is mostly a mechanical change via sed(1)
with some manual fixes where functions for `strbuf` and `reftable_buf`
differ. The converted code does not yet handle allocation failures. This
will be handled in subsequent commits.

We're about to introduce our own `reftable_buf` type to replace
`strbuf`. One function we'll have to convert is `strbuf_addf()`, which
is used in a handful of places. This function uses `snprintf()`
internally, which makes porting it a bit more involved:
- It is not available on all platforms.
- Some platforms like Windows have broken implementations.
So by using `snprintf()` we'd also push the burden on downstream users
of the reftable library to make available a properly working version of
it.
Most callsites of `strbuf_addf()` are trivial to convert to not using
it. We do end up using `snprintf()` in our unit tests, but that isn't
much of a problem for downstream users of the reftable library.
While at it, remove a useless call to `strbuf_reset()` in
`t_reftable_stack_auto_compaction_with_locked_tables()`. We don't write
to the buffer before this and initialize it with `STRBUF_INIT`, so there
is no need to reset anything.

Handle trivial allocation failures in the reftable library and its unit
tests.

Handle allocation failures in `block_writer_init()` and
`block_reader_init()`. This requires us to bubble up error codes into
`writer_reinit_block_writer()`. Adapt call sites accordingly.

The code path for compacting reftable files saw some bugfixes
against concurrent operation.
* ps/reftable-concurrent-compaction:
reftable/stack: fix segfault when reload with reused readers fails
reftable/stack: reorder swapping in the reloaded stack contents
reftable/reader: keep readers alive during iteration
reftable/reader: introduce refcounting
reftable/stack: fix broken refnames in `write_n_ref_tables()`
reftable/reader: inline `reader_close()`
reftable/reader: inline `init_reader()`
reftable/reader: rename `reftable_new_reader()`
reftable/stack: inline `stack_compact_range_stats()`
reftable/blocksource: drop malloc block source

This is conceptually the same as the cases in df9d638c24 (unit-tests:
ignore unused argc/argv, 2024-08-17), but this unit test was migrated
from the reftable tests in a parallel branch.

In the current testing setup, block operations are left unexercised
for index blocks. Add a test that exercises these operations for
index blocks.

Currently, there are two variables for array indices, 'i' and 'j'.
The variable 'j' is used only once and can be easily replaced with
'i'. Get rid of 'j' and replace its occurence with 'i'.

Use xstrfmt() to assign a formatted string to a ref record's
refname instead of xstrdup(). This helps save the overhead of
a local 'char' buffer as well as makes the test more compact.

block_iter_reset() restores a block iterator to its state at the time
of initialization without freeing any memory while block_iter_close()
deallocates the memory for the iterator.
In the current testing setup, a block iterator is allocated and
deallocated for every iteration of a loop, which hurts performance.
Improve upon this by using block_iter_reset() at the start of each
iteration instead. This has the added benifit of testing
block_iter_reset(), which currently remains untested.
Similarly, remove reftable_record_release() for a reftable record
that is still in use.

In the current testing setup, the record key required for many block
iterator functions is manually stored in a strbuf struct and then
passed to these functions. This is not ideal when there exists a
dedicated function to encode a record's key into a strbuf, namely
reftable_record_key(). Use this function instead of manual encoding.

In the current testing setup, operations like read and write for
reftable blocks as defined by reftable/block.{c, h} are verified by
comparing only the keys of input and output reftable records. This is
not ideal because there can exist inequal reftable records with the
same key. Use the dedicated function for record comparison,
reftable_record_equal(), instead of key-based comparison.

Used block readers must be released using block_reader_release() to
prevent the occurence of a memory leak. Make test_block_read_write()
conform to this statement.

Harmonize the newly ported test unit-tests/t-reftable-block.c
with the following guidelines:
- Single line 'for' statements must omit curly braces.
- Structs must be 0-initialized with '= { 0 }' instead of '= { NULL }'.
- Array sizes and indices should preferably be of type 'size_t'and
not 'int'.
- Return code variable should preferably be named 'ret', not 'n'.

reftable/block_test.c exercises the functions defined in
reftable/block.{c, h}. Migrate reftable/block_test.c to the unit
testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework and renaming the tests to follow the unit-tests'
naming conventions.
