Fix loading packed objects >2G
Parsing the size from a packed object header was incorrectly computing
the total inflated length when the length exceeded the range of a Java
int. The next 7 bits of size information was shifted left as an int
using a shift of 25 bits, placing the higher bits of the size into the
sign position. When this size was extended to a long to be added to
the current size accumulator the size went negative, resulting in
NegativeArraySizeException being thrown.

Sort Config entries and use O(log N) lookup
Decrease running time for getStringList (and all other get methods) by
looking for configuration entries using binary search rather than
linear search through the configuration file.
Configuration lines are sorted by section, subsection, name in a

locate an index in the middle of the values, then walk backwards to
find the first value in the range.
Given a configuration of file of 5000 distinct section/subsection/name

Clarify the purpose of ObjectInserter.buffer()
Recently Robin tried to increase the size of the buffer used by

The purpose of this buffer is NOT to make a random InputStream work

Clarify the Javadoc on the buffer() method to reduce the risk

Auto CRLF isn't special enough to be screwing around with the buffers
used for raw byte processing of the ObjectInserter API. If it needs a
buffer to process a file that is bigger than the buffer allocated by
an ObjectInserter, it needs to do its own buffer management.

Only unstash files changed when originally stashed
Previously a DirCacheCheckout was done using a merge tree reflecting
the state of the repository when the stash was originally done.
This was wrong since unstashing after making subsequent commits
would undo changes already committed by checking out entries from
an outdated tree.
The new approach is to scan for conflicts initially using a 6-way
tree walk that contains the trees for the stashed HEAD, stashed
index, stashed working directory, current HEAD, current index, and
current working directory. Then perform a subsequent scan of the
stashed HEAD, index, and working directory trees and apply all
the stashed differences to the current index and working directory.

Enable smart HTTP transport to place EOF at end of pack
When fetching over smart HTTP the InputStream that gets fed into
a PackParser doesn't really support EOF at the end of the pack. It
instead tries to make a new HTTP request, which fails because there

Make EOF work correctly on the end of an HTTP derived InputStream

Smart HTTP support doesn't automatically enqueue execute support onto
the end of the UnionInputStream, which allows the UnionInputStream
