independent of the gitprefix, so get rid of this unused code.

FS_POSIX: Rework umask detection to make it settable
Avoid always calling `sh -c umask` on startup, instead deferring
the invocation until the first time a working tree file needs to
use the execute bit. This allows servers using bare repos to avoid
a costly fork+exec for a value that is never used.
Store the umask as an int instead of two Boolean. This is slightly
smaller memory (one int vs. two references) and makes it easier for
an application to force setting the umask to a value that overrides
whatever the shell told JGit.
Simplify the code to bail by returning early when canExecute is
false, which is the common case for working tree files.

Since git-core ff5effd (v1.7.12.1) the native wire protocol transmits
the server and client implementation and version strings using
capability "agent=git/1.7.12.1" or similar.
Support this in JGit and hang the implementation data off UploadPack
and ReceivePack. On HTTP transports default to the User-Agent HTTP
header until the client overrides this with the optional capability
string in the first line.
Extract the user agent string into a UserAgent class under transport
where it can be specified to a different value if the application's
build process has broken the Implementation-Version header in the
JGit package.

Most callers/users of TemporaryBuffer are sizing the in-memory
portion large enough that most outputs fit into RAM. With this
assumption they don't pay close attention to the size of IOs
being written, as it "should" just be a copy from one byte array
to another.
Overflow sets up a local file handle, which is costly to write to
for small IO units. Wrap the local file in a BufferedOutputStream
to combine small writes together. Larger writes can still bypass the
buffer as BOS automatically avoids copying for larger writes.

TemporaryBuffer: Clear block pointer list instead of reallocating
The block pointer list may have been relatively large, so no need to
make more garbage. Instead, just clear the list and null out all the
elements.
Another possible motivation: a caller may have provided an inaccurate
estimated size, so the list might have been resized several times. If
the list is reused later for a similarly underestimated workload, this
fix will prevent additional resizing on subsequent usages.

TemporaryBuffer: Allow presizing block pointer list
Callers may wish to use TemporaryBuffer as an essentially unbounded
buffer by passing Integer.MAX_VALUE as the size. (This makes it
behave like ByteArrayOutputStream, only without requiring contiguous
memory.) Unfortunately, it was always allocating an array in the
backing block pointer list to hold enough blocks to MAX_VALUE--all
262,016 of them. It wasn't allocating the blocks themselves, but this
array was still extremely wasteful, using about 2MiB of memory on a
64-bit system.
Tweak the interface to specify an estimated size, and only allocate
the block pointer list enough entries to hold that size. It's an
ArrayList, so if that estimate was wrong, it'll grow. We assume the
cost of finding enough contiguous memory to grow that array is
acceptable.
While we're in there, fix an off-by-one error: due to integer division
we were undercounting the number of blocks needed to store n bytes of
data as (n / SZ).

ArchiveCommand: Allow to pass options to underlying stream
Current ArchiveCommand design doesn't allow to pass in options to
underlying stream implementations. To overcome this, client has to
implement custom format implementation (it cannot be derived from
the existing one, because the classes are marked as final), and set
the options using ThreadLocal, before the method
ArchiveOutputStream createArchiveOutputStream(OutputStream s)
is get called.
This change extends the ArchiveCommand.Format by allowing to pass
option map during creation of ArchiveOutputStream.
ArchiveCommand is extended correspondingly. That way client can
easily pass options to the underlying streams:
Map<String, Object> level = ImmutableMap.<String, Object> of(
"level", new Integer(9));
new ArchiveCommand(repo)
.setFormat("zip")
.setFormatOptions(level)
.setTree(tree)
.setPaths(paths)
.setPrefix(prefix)
.setOutputStream(sidebandOut)
.call();

Move checkPath from DirCacheCheckout to ObjectChecker
The bulk of the "is this sane" logic is inside of ObjectChecker. The
only caller for the version in DirCacheCheckout is an obtuse usage for
the static isValidRefName() method in Repository.
Deprecate the weird single use method in DirCacheCheckout and move all
code for checking a sequence of path components into ObjectChecker,
where it makes sense alongside the existing code that checks a single
component at a time.
Reuse a single ObjectChecker for the local platform, to avoid looking
up the system properties on each path string considered.

Adds a factory class for GSSManager. GSSManager is already a factory class but
it doesn't work well with SPNEGO HTTP authentication unless the
javax.security.auth.useSubjectCredsOnly system property is set to false.
On Sun JDK, Sun GSSManagerImpl can be configured directly for SPNEGO auth
(without setting any system property). For a better experience, the class
availability is detected by reflection and used instead.
Detection is only done once, and fallbacks to org.ietf.jgss.GSSManager.

Previously all HTTP communication was done with the help of
java.net.HttpUrlConnection. In order to make JGit usable in environments
where the direct usage of such connections is not allowed but where the
environment provides other means to get network connections an
abstraction for connections is introduced. The idea is that new
implementations of this interface will be introduced which will not use
java.net.HttpUrlConnection but use e.g.
org.apache.client.http.HttpClient to provide network connections.
One example: certain cloud infrastructures don't allow that components
in the cloud communicate directly with HttpUrlConnection. Instead they
provide services where a component can ask for a connection (given a
symbolic name for the destination) and where the infrastructure returns
a preconfigured org.apache.http.client.HttpClient. In order to allow
JGit to be running in such environments we need the abstraction
introduced in this commit.
