a625b092cc branch: correctly reject refs/heads/{-dash,HEAD}
strbuf_check_branch_ref() is the central place where many codepaths
see if a proposed name is suitable for the name of a branch.  It was
designed to allow us to get stricter than the check_refname_format()
check used for refnames in general, and we already use it to reject
a branch whose name begins with a '-'.  The function gets a strbuf
and a string "name", and returns non-zero if the name is not
appropriate as the name for a branch.  When the name is good, it
places the full refname for the branch with the proposed name in the
strbuf before it returns.

However, it turns out that one caller looks at what is in the strbuf
even when the function returns an error.  Make the function populate
the strbuf even when it returns an error.  That way, when "-dash" is
given as name, "refs/heads/-dash" is placed in the strbuf when
returning an error to copy_or_rename_branch(), which notices that
the user is trying to recover with "git branch -m -- -dash dash" to
rename "-dash" to "dash".

While at it, use the same mechanism to also reject "HEAD" as a
branch name.

f28e36686a link_alt_odb_entries: make empty input a noop
If an empty string is passed to link_alt_odb_entries(), our
loop finds no entries and we link nothing. But we still do
some preparatory work to normalize the object directory
path, even though we'll never look at the result. This
triggers in basically every git process, since we feed the
usually-empty ALTERNATE_DB_ENVIRONMENT to the function.

Let's detect early that there's nothing to do and return.
While we're at it, let's treat NULL the same as an empty
string as a favor to our callers. That saves
prepare_alt_odb() from having to cover this case.

049e64aa50 Documentation: convert SubmittingPatches to AsciiDoc
The SubmittingPatches document is often cited by outside parties as an
example of good practices to follow, including logical, independent
commits; patch sign-offs; and sending patches to a mailing list.
Currently, people who want to cite a particular section tend to either
refer to it by name and let the interested party search through the
document to find it, or link to a given line number on GitHub and hope
the file doesn't change.

Instead, convert the document to AsciiDoc.  Build it as part of the
technical documentation, since it is likely of interest to the same
group of people.  Provide stable links to the sections which outside
parties are likely to want to link to.  Make some minor structural
changes to organize it so that it can be formatted sanely.

Since the makefile needs a .txt extension in order to build with the
rest of the documentation, simply copy the file.  Ignore the temporary
file so it doesn't get checked in accidentally, and remove it as part of
the clean process.  Do this instead of renaming the file so that people
who have already linked to the documentation (who we're trying to help)
don't find their links broken.  Avoid symlinking since Windows will not
like that.

This allows us to render the document as part of the website for the
benefit of others who wish to link to it as well as providing a more
nicely formatted display for our community and potential contributors.

78a6766802 Integrate hash algorithm support with repo setup
In future versions of Git, we plan to support an additional hash
algorithm.  Integrate the enumeration of hash algorithms with repository
setup, and store a pointer to the enumerated data in struct repository.
Of course, we currently only support SHA-1, so hard-code this value in
read_repository_format.  In the future, we'll enumerate this value from
the configuration.

Add a constant, the_hash_algo, which points to the hash_algo structure
pointer in the repository global.  Note that this is the hash which is
used to serialize data to disk, not the hash which is used to display
items to the user.  The transition plan anticipates that these may be
different.  We can add an additional element in the future (say,
ui_hash_algo) to provide for this case.

Include repository.h in cache.h since we now need to have access to
these struct and variable definitions.

f50e766b7b Add structure representing hash algorithm
Since in the future we want to support an additional hash algorithm, add
a structure that represents a hash algorithm and all the data that must
go along with it.  Add a constant to allow easy enumeration of hash
algorithms.  Implement function typedefs to create an abstract API that
can be used by any hash algorithm, and wrappers for the existing SHA1
functions that conform to this API.

Expose a value for hex size as well as binary size.  While one will
always be twice the other, the two values are both used extremely
commonly throughout the codebase and providing both leads to improved
readability.

Don't include an entry in the hash algorithm structure for the null
object ID.  As this value is all zeros, any suitably sized all-zero
object ID can be used, and there's no need to store a given one on a
per-hash basis.

The current hash function transition plan envisions a time when we will
accept input from the user that might be in SHA-1 or in the NewHash
format.  Since we cannot know which the user has provided, add a
constant representing the unknown algorithm to allow us to indicate that
we must look the correct value up.  Provide dummy API functions that die
in this case.

Finally, include git-compat-util.h in hash.h so that the required types
are available.  This aids people using automated tools their editors.

abade65b79 setup: expose enumerated repo info
We enumerate several different items as part of struct
repository_format, but then actually set up those values using the
global variables we've initialized from them.  Instead, let's pass a
pointer to the structure down to the code where we enumerate these
values, so we can later on use those values directly to perform setup.

This technique makes it easier for us to determine additional items
about the repository format (such as the hash algorithm) and then use
them for setup later on, without needing to add additional global
variables.  We can't avoid using the existing global variables since
they're intricately intertwined with how things work at the moment, but
this improves things for the future.

2fff1e196d grep: fix NO_LIBPCRE1_JIT to fully disable JIT
If you have a pcre1 library which is compiled with JIT enabled then
PCRE_STUDY_JIT_COMPILE will be defined whether or not the
NO_LIBPCRE1_JIT configuration is set.

This means that we enable JIT functionality when calling pcre_study
even if NO_LIBPCRE1_JIT has been explicitly set and we just use plain
pcre_exec later.

Fix this by using own macro (GIT_PCRE_STUDY_JIT_COMPILE) which we set to
PCRE_STUDY_JIT_COMPILE only if NO_LIBPCRE1_JIT is not set and define to
0 otherwise, as before.

5555a2aa4b t4201: make use of abbreviation in the test more robust
The test for '--abbrev' in t4201-shortlog.sh assumes that the commits
generated in the test can always be uniquely abbreviated to 5 hex digits
but this is not always the case. If you were unlucky and happened to run
the test at (say) Thu Jun 22 03:04:49 2017 +0000, you would find that
the first commit generated would collide with a tree object created
later in the same test.

This can be simulated in the version of t4201-shortlog.sh prior to this
commit by setting GIT_COMMITTER_DATE and GIT_AUTHOR_DATE to 1498100689
after sourcing test-lib.sh.

Change the test to test --abbrev=35 instead of --abbrev=5 to almost
completely avoid the possibility of a partial collision and add a call
to test_tick in the setup to make the test repeatable (the latter alone
is sufficient to make it robust enough).
