This code is only needed for diff-tree (since f0c6b2a2fd ([PATCH]
Optimize diff-tree -[CM] --stdin - 2005-05-27)). Let the caller do the
preparation instead and avoid read_index() in diff.c code.
read_index() should be avoided (in addition to the_index) because it
uses get_index_file() underneath to get the path $GIT_DIR/index. This
effectively pulls the_repository in and may become the only reason to
pull a 'struct repository *' in diff.c. Let's keep the dependencies as
few as possible and kick it back to diff-tree.c

The lazy clone support had a few places where missing but promised
objects were not correctly tolerated, which have been fixed.
* jt/tags-to-promised-blobs-fix:
tag: don't warn if target is missing but promised
revision: tolerate promised targets of tags
|

Add a server-side knob to skip commits in exponential/fibbonacci
stride in an attempt to cover wider swath of history with a smaller
number of iterations, potentially accepting a larger packfile
transfer, instead of going back one commit a time during common
ancestor discovery during the "git fetch" transaction.

negotiator/skipping: skip commits during fetch

"git send-email" when using in a batched mode that limits the
number of messages sent in a single SMTP session lost the contents
of the variable used to choose between tls/ssl, unable to send the
second and later batches, which has been fixed.
* jm/send-email-tls-auth-on-batch:
send-email: fix tls AUTH when sending batch

"git rebase" started exporting GIT_DIR environment variable and
exposing it to hook scripts when part of it got rewritten in C.
Instead of matching the old scripted Porcelains' behaviour,
compensate by also exporting GIT_WORK_TREE environment as well to
lessen the damage. This can harm existing hooks that want to
operate on different repository, but the current behaviour is
already broken for them anyway.
* bc/sequencer-export-work-tree-as-well:
sequencer: pass absolute GIT_WORK_TREE to exec commands

added for merge-recursive.

The recursive merge strategy did not properly ensure there was no
change between HEAD and the index before performing its operation,
which has been corrected.
* en/dirty-merge-fixes:
merge: fix misleading pre-merge check documentation
merge-recursive: enforce rule that index matches head before merging
t6044: add more testcases with staged changes before a merge is invoked

"git gc --auto" opens file descriptors for the packfiles before
spawning "git repack/prune", which would upset Windows that does
not want a process to work on a file that is open by another
process. The issue has been worked around.
* kg/gc-auto-windows-workaround:
gc --auto: release pack files before auto packing

For a large tree, the index needs to hold many cache entries
allocated on heap. These cache entries are now allocated out of a
dedicated memory pool to amortize malloc(3) overhead.

block alloc: allocate cache entries from mem_pool
mem-pool: fill out functionality
mem-pool: add life cycle management functions
mem-pool: only search head block for available space
block alloc: add lifecycle APIs for cache_entry structs
read-cache: teach make_cache_entry to take object_id
read-cache: teach refresh_cache_entry to take istate

"git fetch" learned a new option "--negotiation-tip" to limit the
set of commits it tells the other end as "have", to reduce wasted
bandwidth and cycles, which would be helpful when the receiving
repository has a lot of refs that have little to do with the
history at the remote it is fetching from.
* jt/fetch-nego-tip:
fetch-pack: support negotiation tip whitelist

"git pull --rebase" on a corrupt HEAD caused a segfault. In
general we substitute an empty tree object when running the in-core
equivalent of the diff-index command, and the codepath has been
corrected to do so as well to fix this issue.

has_uncommitted_changes(): fall back to empty tree

This character class, like many others in this script, matches
horizontal whitespace consisting of spaces and tabs, however, a few
extra, entirely harmless, spaces somehow slipped into the expression.
Removing them is purely a cosmetic fix.
While at it, re-indent three lines with a single TAB each which were
incorrectly indented with six spaces. Also, a purely cosmetic fix.
