DirCacheCheckout is generating names for temporary files. It was not checking
the length of this filenames. It may happen that a generated filename is
longer than 255 chars which causes problems on certain platforms. Make sure
that filenames for temporary files do not exceed 255 chars.

Some repository topologies can cause carryOntoHistory to overflow the
thread stack, due to its strategy of recursing into the 2nd+ parents
of a merge commit. This can easily happen if a project maintains a
local fork, and frequently pulls from the upstream repository, which
itself may have a branchy history.
Rewrite the carryOntoHistory algorithm to use a fixed amount of thread
stack, pushing the save points onto the heap. By using heap space the
thread stack depth is no longer a concern. Repositories are instead
limited by available memory.
The algorithm is now structured as two loops:
carryOntoHistory: This outer loop pops saved commits off the top of
the stack, allowing the inner loop algorithm to dive down that path
and carry bits onto commits along that part of the graph. The loop
ends when there are no more stack elements.
carryOntoHistoryInner: The inner loop walks along a single path of
the graph. For a string of pearls (commits with one parent each)
r <- s <- t <- u
the algorithm walks backwards from u to r by iteratively updating
its local variable 'c'. This avoids heap allocation along a simple
path that does not require remembering state.
The inner loop breaks in the HAVE_ALL case, when all bits have been
found to be previously set on the commit. This occurs when a prior
iteration of the outer loop (carryOntoHistory) explored a different
path to this same commit, and copied the bits onto it.
When the inner loop encounters a merge commit, it pushes all parents
onto the heap based stack by allocating individual CarryStack
elements for each parent. Parents are pushed in order, allowing
side branches to be explored first.
A small optimization is taken for the last parent, avoiding pushing
it and instead updating 'c', allowing the side branch to be entered
without allocating a CarryStack.

Delete the condition to check whether the garbage pack creation time
is older than the last GC operation, because it's not possible to
find the last GC operation time when there is no GC pack.
Add additional tests to make sure the contents of the expired garbage
packs are considered during the GC operation and any actively
referenced objects from the garbage packs are copied successfully
into the GC pack before deleting the garbage pack.

Android wants them to work, and we're only interested in them for bare
repos, so add them just for that.
Make sure to use symlinks instead of just using the copyfile
implementation. Some scripts look up where they're actually located in
order to find related files, so they need the link back to their
project.

Because objects described by the client using "have" lines do not need
to be reachable by any ref on the server, it is possible for them to
point to missing objects in the reachability graph. When such an
object is encountered, I1097a2defa4a9dcf502ca8baca5d32880378818f (Only
throw MissingObjectException when necessary, 2017-03-29) aborts the
"have" walk early to salvage the fetch. The downside of that change
is that remaining "have"s are ignored unless they pointed directly to
an object with a bitmap. In the worst case this can increase the
bandwidth cost of a fetch to the cost of a clone because most "have"s
are ignored.
Avoid this cost by bypassing the failed "have" completely and moving
on to the remaining "have"s.

Generating the src list with an unrestricted wildcard causes all

such as .orig (generated during merge conflict resolution) to be
included, which causes in a build error:

This is necessary for deploying submodules on android.googlesource.com.
* Allow an empty base URL. This is useful if the 'fetch' field is "."
and all names are relative to some host root.
* The URLs in the resulting superproject are relative to the
superproject's URL. Add RepoCommand#setDestinationURI to
set this. If unset, the existing behavior is maintained.
* Add two tests for the Android and Gerrit case, checking the URL
format in .gitmodules; the tests use a custom RemoteReader which is
representative of the use of this class in Gerrit's Supermanifest
plugin.
