Partial clone support of "git clone" has been updated to correctly
validate the objects it receives from the other side. The server
side has been corrected to send objects that are directly
requested, even if they may match the filtering criteria (e.g. when
doing a "lazy blob" partial clone).
* jt/partial-clone-fsck-connectivity:

"git fetch" failed to correctly validate the set of objects it
received when making a shallow history deeper, which has been
corrected.

When we initially added the strbuf_readlink() function in
b11b7e13f4 (Add generic 'strbuf_readlink()' helper function,
2008-12-17), the point was that we generally have a _guess_
as to the correct size based on the stat information, but we
can't necessarily trust it.
Over the years, a few callers have grown up that simply pass
in 0, even though they have the stat information. Let's have
them pass in their hint for consistency (and in theory
efficiency, since it may avoid an extra resize/syscall loop,
but neither location is probably performance critical).
Note that st.st_size is actually an off_t, so in theory we
need xsize_t() here. But none of the other callsites use it,
and since this is just a hint, it doesn't matter either way
(if we wrap we'll simply start with a too-small hint and
then eventually complain when we cannot allocate the
memory).

When performing tag following, in addition to using the server's
"include-tag" capability to send tag objects (and emulating it if the
server does not support that capability), "git fetch" relies upon the
presence of refs/tags/* entries in the initial ref advertisement to
locally create refs pointing to the aforementioned tag objects. When
using protocol v2, refs/tags/* entries in the initial ref advertisement
may be suppressed by a ref-prefix argument, leading to the tag object
being downloaded, but the ref not being created.
Commit dcc73cf7ff ("fetch: generate ref-prefixes when using a configured
refspec", 2018-05-18) ensured that "refs/tags/" is always sent as a ref
prefix when "git fetch" is invoked with no refspecs, but not when "git
fetch" is invoked with refspecs. Extend that functionality to make it
work in both situations.
This also necessitates a change another test which tested ref
advertisement filtering using tag refs - since tag refs are sent by
default now, the test has been switched to using branch refs instead.

Many messages will be marked for translation in the following
commits. This commit updates some of them to be more consistent and
reduce diff noise in those commits. Changes are
- keep the first letter of die(), error() and warning() in lowercase
- no full stop in die(), error() or warning() if it's single sentence
messages
- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will
not be marked for i18n
- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly
(on the same token, combine multiple warning() into one big string)
- the trailing \n is converted to printf_ln if possible, or deleted
if not redundant
- errno_errno() is used instead of explicit strerror()

Because the commit graph functions can now read the commit graph of any
repository, the global variable core_commit_graph has been removed.
Instead, the config option core.commitGraph is now read on the first
time in a repository that a commit is attempted to be parsed using its
commit graph.
This commit includes a test that exercises the functionality on an
arbitrary repository that is not the_repository.

Our color buffers are all COLOR_MAXLEN, which fits the
largest possible color. So we can never overflow the buffer
by copying an existing color. However, using strcpy() makes
it harder to audit the code-base for calls that _are_
problems. We should use something like xsnprintf(), which
shows the reader that we expect this never to fail (and
provides a run-time assertion if it does, just in case).

`git merge-recursive` does a three-way merge between user-specified trees
base, head, and remote. Since the user is allowed to specify head, we can
not necesarily assume that head == HEAD.
Modify index_has_changes() to take an extra argument specifying the tree
to compare against. If NULL, it will compare to HEAD. We then use this
from merge-recursive to make sure we compare to the user-specified head.
