This method only creates an EolCanonicalizingInputStream
which does not throw an IOException and so the throws
declaration on the method is unneeded.

DirCacheCheckout and CanonicalTreeParser cooperate. CanonicalTreeParser
can detect malformed, potentially malicious tree entries and sets a
flag, while DirCacheCheckout refuses to work with such paths.
Malicious tree entries are ".", "..", ".git" (case insensitive), any
name containing '/' and (on Windows '\') and also (on Windows)
any paths ending in a combination of '.' or space or containing a ':'.
We also forbid all special names like "con" etc on Windows.
Some of the test can execute on any platform by enabling partial
platform emulation.
A new runtime exception, InvalidPathException, is introduced. For
backwards compatibility it extends InvalidArgumentException.

Java NIO has some problems (like files closing unexpectedly because the
thread was interrupted). To avoid those problems, don't use a NIO
channel to determine the size of a file, but rather ask the File itself.
We have to be prepared to handle wrong/outdated information in this case
too, as the inode of the File may change between opening and determining
file size.

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.
Fix all places where this particular pattern of code is used to read a
pack size field, or a binary delta header, as they both use the same
variable length encoding scheme.

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
sorted list whenever the snapshot is rebuilt. Binary search is used to
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
triplets (e.g. a Gerrit Code Review project.config configuration file
with 5000 unique access control rules), this new code is faster to
lookup each rule individually using getStringList():
old setStringList() 194 usec avg
getStringList() 196 usec avg
new setStringList() 188 usec avg
getStringList() 24 usec avg

RefDirectory into a new ReflogWriter class. This class
creates a public API for writing reflog entries similar
to ReflogReader for reading reflog entries.
The new command supports rewriting the stash's log to remove
a configured entry followed by updating the stash ref to
the value at the bottom of the newly written log.

Recently Robin tried to increase the size of the buffer used by
ObjectInserter to fix a bug in the InputStream that handles AutoCRLF.
The purpose of this buffer is NOT to make a random InputStream work
correctly by passing it a larger buffer during read(byte[],int,int).
Clarify the Javadoc on the buffer() method to reduce the risk
someone tries to abuse it again.
While we are here, modify the method to load the field into a local
variable before returning. This should cut down 1 field load during
the common case of the buffer being already allocated.

This reverts commit 88fe2836ed.
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.

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.

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
is no request body currently buffered by the client.
Make EOF work correctly on the end of an HTTP derived InputStream
for the pack by denoting no more requests are expected as the higher
level code is now consuming the pack (or side-band embedded pack).
Smart HTTP support doesn't automatically enqueue execute support onto
the end of the UnionInputStream, which allows the UnionInputStream
to correctly reflect EOF when the HTTP response is consumed.

When a client POSTs to /git-{upload,receive}-pack, the first line
includes their client capabilities. As soon as the C git client sends
side-band(-64k), it goes into a state where it chokes on data not sent
in a valid sideband channel.
GitSmartHttpTools.sendError() is called early in the request, likely
before a {Upload,Receive}Pack handler is assigned or, even so, before it
has read the request. In some cases we must read the first line manually
within sendError() to tell whether sideband is needed.
