Taylor Blau 4571324b99 builtin/repack.c: allow configuring cruft pack generation
In servers which set the pack.window configuration to a large value, we
can wind up spending quite a lot of time finding new bases when breaking
delta chains between reachable and unreachable objects while generating
a cruft pack.

Introduce a handful of `repack.cruft*` configuration variables to
control the parameters used by pack-objects when generating a cruft
pack.

repack.useDeltaBaseOffset::
By default, linkgit:git-repack[1] creates packs that use
delta-base offset. If you need to share your repository with
Git older than version 1.4.4, either directly or via a dumb
protocol such as http, then you need to set this option to
"false" and repack. Access from old Git versions over the
native protocol are unaffected by this option.
repack.packKeptObjects::
If set to true, makes `git repack` act as if
`--pack-kept-objects` was passed. See linkgit:git-repack[1] for
details. Defaults to `false` normally, but `true` if a bitmap
index is being written (either via `--write-bitmap-index` or
`repack.writeBitmaps`).
repack.useDeltaIslands::
If set to true, makes `git repack` act as if `--delta-islands`
was passed. Defaults to `false`.
repack.writeBitmaps::
When true, git will write a bitmap index when packing all
objects to disk (e.g., when `git repack -a` is run). This
index can speed up the "counting objects" phase of subsequent
packs created for clones and fetches, at the cost of some disk
space and extra time spent on the initial repack. This has
no effect if multiple packfiles are created.
Defaults to true on bare repos, false otherwise.
repack.updateServerInfo::
If set to false, linkgit:git-repack[1] will not run
linkgit:git-update-server-info[1]. Defaults to true. Can be overridden
when true by the `-n` option of linkgit:git-repack[1].
repack.cruftWindow::
repack.cruftWindowMemory::
repack.cruftDepth::
repack.cruftThreads::
Parameters used by linkgit:git-pack-objects[1] when generating
a cruft pack and the respective parameters are not given over
the command line. See similarly named `pack.*` configuration
variables for defaults and meaning.
