I believe it cannot hurt to be slightly more explicit about how
to retrieve API calls and provide examples.

Instead of just removing the store.db directory, remove everything so
that --mkfs can re-create it instead of infering that it already exists.

A mon is considered to exist if the mon-data directory exists and is not
empty. If ceph-mon --mkfs is run twice, it will display succeed the
second time around and display an informative message.

Each of btrfs and zfs backends are wrapped in if __linux__ and if
WITH_ZFS, respectively, resulting in empty object files and the
associated warnings. This builds them under the same conditions.

According to this https://code.google.com/p/googletest/source/detail?r=446
the use of unnamed types (in this case the protection flag enums from
librbd/parent_types.h) as template parameters (in this case the gtest
macros) is not valid C++ pre C++0x.
As suggested, converting the enum into an int with integral promotion
via unary plus operator solves the problem.

This removes export-symbol-regex for installed libraries with C++
interfaces on non-Linux where the hidden symbols are not resolved. This
is a temporary fix.
See ceph-devel topic "Shared library symbol visibility" for discussion
about a perm solution.

This file just includes the header that is full of templates and
typedefs, so the resulting object file has no symbols in it and
generates warnings.

On OSX there is consistently a problem with resolving pipe_cloexec and other
symbols through indirect libtool dependencies (below libglobal has a dependency
on libcommon). This makes the dependency top-level for most executables.
CXXLD ceph_test_timers
Undefined symbols for architecture x86_64:
"_pipe_cloexec", referenced from:
AdminSocket::create_shutdown_pipe(int*, int*) in libglobal.a(admin_socket.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

* The 'buf' argument to read() used to be passed into
AioCompletionImpl, and the results would be copied back after
reading. This is replaced with the creation of a static buffer of
that buf.
* The pbl argument in AioCompletionImpl is removed.
The patch is tested against an application using librados. I've
assumed that 'pbl' in
aio_read( ...., pbl, )
is allocated by the user. It may even speed things up: a buffer copy
is prevented.

The content of CEPH_ARGS is appended to the list of arguments. When
--show-config or --show-config-value is also set, it should be evaluated
after all arguments are parsed to accurately reflect the value that
would be visible to the program.
It failed to do so because the action for --show-config* was carried out
immediately. It is postponed until all options are parsed instead.

If not set, commands that rely on --show-config-value fsid or something
equivalent will fail. ceph-disk does, for instance and setting the fsid
in CEPH_ARGS won't help because it will be appended after
--show-config-value :
CEPH_ARGS="--fsid 96a3abe6-7552-4635-a79b-f3c096ff8b95" ./ceph-mon --cluster=ceph --name=osd. --show_args --show-config-value fsid

Not all compilers are supporting tr1/tuple. This forces libgtest to use
an internal implementation of tuple. Alternatively, the newer 1.6
version of gtest may correctly handle this case automatically.

Unfortunately, 'using namespace std;' is in pretty widespread use in the Ceph
tree, so we need to rename to avoid the conflict.
Example error output:

Mutex::Locker l(lock);
^
test/streamtest.cc:32:7: note: candidate found by name lookup is 'lock'

There are several non-standard errno values used. There is still work to
do on addressing errno portability in Ceph, and this disables kvstore on
non-Linux platforms until that work is complete.

Adds a ceph_spinlock_t implementation that will use pthread_spinlock_t
if available, and otherwise reverts to pthread_mutex_t. Note that this
spinlock is not intended to be used in process-shared memory.
Switches implementation in:
ceph_context
SimpleMessenger
atomic_t
Only ceph_context initialized its spinlock with PTHREAD_PROCESS_SHARED.
However, there does not appear to be any instance in which CephContext
is allocated in shared memory, and thus can use the default private
memory space behavior.
