test-sha1-array uses the_hash_algo under the hood. Since t0064 wants to
use the value that is correct for the hash algorithm that we're testing,
make sure the test helper initializes the repository to set
the_hash_algo correctly.

14ba97f8 (alloc: allow arbitrary repositories for alloc functions,
2018-05-15) introduced parsed_object_pool->commit_count to keep count of
commits per repository and was used to assign commit->index.
However, commit-slab code requires commit->index values to be unique
and a global count would be correct, rather than a per-repo count.
Let's introduce a static counter variable, `parsed_commits_count` to
keep track of parsed commits so far.
As commit_count has no use anymore, let's also drop it from the struct.

In a future commit, we will use PACKET_READ_RESPONSE_END to separate

PACKET_READ_RESPONSE_END enum value.

PACKET_READ_RESPONSE_END is unexpected. Otherwise, mirror how
PACKET_READ_DELIM is implemented (especially in cases where packets are
being forwarded).

7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27)
adds a REG_ILLSEQ prerequisite to avoid failures from the tests added in
4e2443b181 (log tests: test regex backends in "--encode=<enc>" tests,
2019-06-28), but hardcodes it to be only enabled in FreeBSD.
Instead of hardcoding the affected platform, teach the test-regex helper,
how to validate a pattern and report back, so it can be used to detect the
same issue in other affected systems (like DragonFlyBSD or macOS).
While at it, refactor the tool so it can report back the source of the
errors it founds, and can be invoked also in a --silent mode, when needed,
for backward compatibility. A missing flag has been added and the code
reformatted, as well as updates to the way the parameters are handled, for
consistency.
To minimize changes, it is assumed the regcomp error is of the right type
since we control the only caller, and is also assumed to affect both basic
and extended syntax (only basic is tested, but both behave the same in all
three affected platforms since they use the same function).

In 61df89c8e5 (commit-graph: don't early exit(1) on e.g. "git status",
2019-03-25), the former 'load_commit_graph_one' was refactored into
'open_commit_graph' and 'load_commit_graph_one_fd_st' as a means of
avoiding an early-exit from non-library code.
However, 'load_commit_graph_one' does not support commit-graph chains,
and hence the 'read-graph' test tool does not work with them.
Replace 'load_commit_graph_one' with 'read_commit_graph_one' in order to
support commit-graph chains. In the spirit of 61df89c8e5,
'read_commit_graph_one' does not ever 'die()', making it a suitable
replacement here.

Add logic to
a) parse Bloom filter information from the commit graph file and,
b) re-use existing Bloom filters.
See Documentation/technical/commit-graph-format for the format in which
the Bloom filter information is written to the commit graph file.
To read Bloom filter for a given commit with lexicographic position
'i' we need to:
1. Read BIDX[i] which essentially gives us the starting index in BDAT for
filter of commit i+1. It is essentially the index past the end
of the filter of commit i. It is called end_index in the code.
2. For i>0, read BIDX[i-1] which will give us the starting index in BDAT
for filter of commit i. It is called the start_index in the code.
For the first commit, where i = 0, Bloom filter data starts at the
beginning, just past the header in the BDAT chunk. Hence, start_index
will be 0.
3. The length of the filter will be end_index - start_index, because
BIDX[i] gives the cumulative 8-byte words including the ith
commit's filter.
We toggle whether Bloom filters should be recomputed based on the
compute_if_not_present flag.

We renamed the actual data structure in 910650d2f8 (Rename sha1_array to
oid_array, 2017-03-31), but the file is still called sha1-array. Besides
being slightly confusing, it makes it more annoying to grep for leftover
occurrences of "sha1" in various files, because the header is included
in so many places.
Let's complete the transition by renaming the source and header files
(and fixing up a few comment references).
I kept the "-" in the name, as that seems to be our style; cf.
fc1395f4a4 (sha1_file.c: rename to use dash in file name, 2018-04-10).
We also have oidmap.h and oidset.h without any punctuation, but those
are "struct oidmap" and "struct oidset" in the code. We _could_ make
this "oidarray" to match, but somehow it looks uglier to me because of
the length of "array" (plus it would be a very invasive patch for little
gain).

Add the core implementation for computing Bloom filters for
the paths changed between a commit and it's first parent.
We fill the Bloom filters as (const char *data, int len) pairs
as `struct bloom_filters" within a commit slab.
Filters for commits with no changes and more than 512 changes,
is represented with a filter of length zero. There is no gain
in distinguishing between a computed filter of length zero for
a commit with no changes, and an uncomputed filter for new commits
or for commits with more than 512 changes. The effect on
`git log -- path` is the same in both cases. We will fall back to
the normal diffing algorithm when we can't benefit from the
existence of Bloom filters.

Introduce the constructs for Bloom filters, Bloom filter keys
and Bloom filter settings.
For details on what Bloom filters are and how they work, refer
to Dr. Derrick Stolee's blog post [1]. It provides a concise
explanation of the adoption of Bloom filters as described in
[2] and [3].
Implementation specifics:
1. We currently use 7 and 10 for the number of hashes and the
size of each entry respectively. They served as great starting
values, the mathematical details behind this choice are
described in [1] and [4]. The implementation, while not
completely open to it at the moment, is flexible enough to allow
for tweaking these settings in the future.
Note: The performance gains we have observed with these values
are significant enough that we did not need to tweak these
settings. The performance numbers are included in the cover letter
of this series and in the commit message of the subsequent commit
where we use Bloom filters to speed up `git log -- path`.
2. As described in [1] and [3], we do not need 7 independent hashing
functions. We use the Murmur3 hashing scheme, seed it twice and
then combine those to procure an arbitrary number of hash values.
3. The filters will be sized according to the number of changes in
each commit, in multiples of 8 bit words.

Returning a shared buffer invites very subtle bugs due to reentrancy or
multi-threading, as demonstrated by the previous patch.
There was an unfinished effort to abolish this [1].
Let's finally rid of `real_path()`, using `strbuf_realpath()` instead.
This patch uses a local `strbuf` for most places where `real_path()` was
previously called.
However, two places return the value of `real_path()` to the caller. For
them, a `static` local `strbuf` was added, effectively pushing the
problem one level higher:
read_gitfile_gently()
get_superproject_working_tree()

Currently it's very easy for the advice library's callers to miss
checking the visibility step before printing an advice. Also, it makes
more sense for this step to be handled by the advice library.
Add a new advise_if_enabled function that checks the visibility of
advice messages before printing.
Add a new helper advise_enabled to check the visibility of the advice
if the caller needs to carry out complicated processing based on that
value.
A list of advice_settings is added to cache the config variables names
and values, it's intended to replace advice_config[] and the global

To be able to give such messages when notifying the user about
configurations in any config file, it is currently only possible to get
the file name (if the value originates from a file to begin with) via
`current_config_name()`. Now it is also possible to query the current line
number for the configuration.

To prepare for the upcoming --show-scope option, we require the ability
to convert a config_scope enum to a string. As this was originally
implemented as a static function 'scope_name()' in
t/helper/test-config.c, we expose it via config.h and give it a less
ambiguous name 'config_scope_name()'
