When we are cloning we have no refs at all yet, and there cannot
(or at least should not) be any other thread doing something with
refs yet.
Locking loose refs is thus not needed, since there are no loose
refs yet and nothing should be trying to create them concurrently.
Let's skip the whole loose ref locking when we are cloning a repository.
As a result, JGit will write the refs directly to the packed-refs
file, and will not create the refs/remotes/ directories nor the
lock files underneath when cloning and packed refs are used. Since
no lock files are created, any problems on case-insensitive file
systems with tag or branch names that differ only in case are avoided
during cloning.
Detect if we are cloning based on the following heuristics:
* HEAD is a dangling symref
* There is no loose ref
* There is no packed-refs file
Note, however, that there may still be problems with such tag or
branch names later on. This is primarily a five-minutes-past-twelve
stop-gap measure to resolve the referenced bug, which affects the
Oxygen.2 release.

Config: Remove the include functionality
Merged with "-s ours" because the fix on stable conflicts with
the fix already done here.

The Config class must be safe to run against untrusted input files.
Reading arbitrary local system paths using include.path is risky for
servers, including Gerrit Code Review.
This was fixed on master [1] by making "readIncludedConfig" a noop
by default. This allows only FileBasedConfig, which originated from
local disk, to read local system paths.
However, the "readIncludedConfig" method was only introduced in [2]
which was needed by [3], both of which are only on the master branch.
On the stable branch only Config supports includes. Therefore this
commit simply disables the include functionality.

Reading arbitrary local system paths using include.path is risky for
servers, including Gerrit Code Review. Return null by default to
incide the include should be ignored.
Only FileBasedConfig which originated from local disk should be trying
to read local system paths. FileBasedConfig already overrides this
method with its own implementation.

This can be useful for sophisticated pre-read algorithms to quickly
determine if a file is likely already in cache, especially small
reftables which may be smaller than a typical DFS block size.

File.listFiles() returns null if the given File does not represent a
directory, so we can just test for null instead of making a separate
call to FS.DETECTED.isDirectory()
This also avoids a false-positive error from SpotBugs which claims
that there is a potential null-pointer exception on dereferencing the
result of Files.listFiles().

Pretty printing the response is useful for human readers, but most
(if not all) of the time, the response will be read by programs.
Remove it to avoid the additional overhead of the formatting and
extra bytes in the response. Adjust the test accordingly.
Note that LfsProtocolServlet already doesn't use pretty printing,
so this change makes FileLfsServlet's behavior consistent. In fact,
both classes now have duplicate Gson handling; this will be cleaned
up in a separate change.

Instead of hard-coding the charset strings "US-ASCII", "UTF-8", and
"ISO-8859-1", use the corresponding constants from StandardCharsets.
UnsupportedEncodingException is not thrown when the StandardCharset
constants are used, so remove the now redundant handling.
Because the encoding names are no longer hard-coded strings, also
remove redundant $NON-NLS warning suppressions.
Also replace existing usages of the constants with static imports.
