The in-tree Hadoop shim was a combination of libcephfs wrapper, and the
bits to support Hadoop. This has been replaced by src/java that
implements generic libcephfs wrappers, and externally, the hadoop shim
(see docs).

Create a new test file covering most (> 97%) of src/os/chain_xattr.{cc,h}
lines of code. The following functions are tested:
int chain_getxattr(const char *fn, const char *name, void *val, size_t size);
int chain_fgetxattr(int fd, const char *name, void *val, size_t size);
int chain_setxattr(const char *fn, const char *name, const void *val, size_t size);
int chain_fsetxattr(int fd, const char *name, const void *val, size_t size);
int chain_listxattr(const char *fn, char *names, size_t len);
int chain_flistxattr(int fd, char *names, size_t len);
int chain_removexattr(const char *fn, const char *name);
int chain_fremovexattr(int fd, const char *name);
The function translate_raw_name substitutes @@ into @. When the trailing
character is a @, it breaks. However, such an occurence cannot be created by
chain_setxattr because it always create pairs of @. Instead of silently
breaking the loop, the function should probably return on error so that the
caller can ignore it.
The function chain_fgetxattr_len may return on error if fgetxattr
returns on error. However, it is only called after another attr function
returned success and the tests cannot create the conditions under which
it would fail.
The function chain_fsetxattr may leak attributes when used to override
an existing attribute. This leak is not tested or fixed, it is just
discussed in http://marc.info/?l=ceph-devel&m=136027076615853&w=4
If the file system in which the tests are run does not support extended
attributes, the tests are not run. The detection uses the same logic as
the one implemented in FileStore::_detect_fs
The output of the tests are silenced to reduce the output when testing
assertions ( except for the dout_emergency function which cannot be
controlled).
Removes a condition in Throttle::_reset_max by which the waiting queue is only
Signal()ed if the new maximum is lower than the current maximum.
There is no evidence of a use case where such a restriction would be
useful. In addition waking up a thread when the maximum increases
gives it a chance to immediately continue the suspended process
instead of waiting for the next put().
Create a new test file covering 100% of src/Throttle.{cc,h} lines of code.
The following methods are tested:
* Throttle::Throttle with and without a maximum
* Throttle::~Throttle when each pending Cond is deleted
* Throttle::take
* Throttle::get when updating the maximum ( lower or higher ),
when going to sleep waiting for the count to lower under
the maximum, when going to sleep because another thread is
already asleep waiting
* Throttle::get_or_fail when there is no maximum,
when requesting a count that is larger than the maximum, either
when the current value is under the maximum or above the maximum.
* Throttle::wait when used to reset the maximum and wake up
another thread asleep waiting
All asserts checking the arguments sanity are exercised ( negative argument
for Throttle::take etc. ).
Adds the LGPLv2+ licensing terms to COPYING along with the others.
Adds a Contributors section to the AUTHORS file.
Notes:
Testing asserts outputs verbose error messages that should be silenced
but it does not seem possible.

This is lightweight and relies on boost spirit, which we already use, so
there are no new dependencies.
There were some other libraries that also looked good, but they weren't
already packages for existing Debian distros like squeeze or even wheezy.

This (mostly) copies debian/copyright for now, but there are format
restrictions for that file. Suggestions for a cleaner way to handle this
are welcome. In the meantime, this is better...
