The input buffer is copied when padding is required. Remove the tests
that ensured the input buffer was not copied entirely when padding was
added.

When coding chunks are allocated for jerasure, their address must be
aligned to page boundaries. The requirement is actually to be aligned on
a long long boundary but bufferlist do not allow for fine tuning of the
alignment.
If padding is necessary because the total size of the data to be encoded
is not a multiple of the alignment requirements as returned by
get_alignment(), the buffer is not only padded but also rebuilt using
rebuild_page_aligned() to preserve the page alignment that is expected
of the input buffer.
The overhead of rebuilding the whole input buffer when padding is
necessary could be reduced by only reallocating one buffer for the last
data chunk, therefore reducing the amount of data being copied. However,
this optimization is not going to be used if the caller takes care of
the padding, which is likely to be the case most of the time.

All tests in daemon_config use the global g_ceph_context
object. Introducing an expansion loop in it will impact all tests and
generate a very large output.
Remove the SubstitutionLoop test case which is also covered in
test/common/test_config.cc.

Fixes: #7083
This was broken when we fixed#6940. We use the same function to both
read the bucket policy and the object policy. However, each needed to be
treated differently. Restore old behavior for objects.

Part of the config.cc tests are in test/confutils.cc but they do not
cover meta variable expansion. Create unittest_config for config.{h,cc}
specific tests.
The test_md_config_t is made a friend of md_config_t to allow testing
private and protected methods.
test/cli/ceph-conf/show-config-value.t is used to check that the human
readable message message shows as expected when there is an expansion
loop.

Using a recursive implementation of variable expansions make it easier
to protect against loops and provide human readable messages when they
happen.
It also enables one variable to be substituted multiple times in the
same configuration option instead of just once because it is confused
with a variable expansion loop.

Adds a class that executes registered callbacks in its destructor. Since
static duration objects have their destructors called when returning
from main or calling exit then this can be used as a replacement for
on_exit.

How to make this portable:
- MAP_ANONYMOUS -> MAP_ANON (OSX)
- sem_init (anonymous semaphore) needs to be replaced by named
semaphores using sem_open/sem_close. Use a memory address of the sem_t
variable to hack anonymous semaphore behavior.
- sem_getvalue isn't supported on OSX. it is used here to do
sem_wait/sem_post to bring a semaphore back to a specific value. to get
around this we may need to restructure the test so that the semaphore
can be destroyed and re-initialized rather than inspected as its
currently being done.

When running "make check", Automake generates test-suite.log, along with

The output of test/ceph-disk.sh is very verbose which is good for
debugging errors. However it sometime contains strings that match
/error:/i which is picked by gitbuilder as a sign that the test fail,
even when the exit code is zero.
Remove from the output the three strings triggering false positive in
gitbuilder.

In cce990efc8 we added a limit to avoid
holding the lock for too long. However, if we back off, we currently
wait for a full second, which is probably a bit much--we really just want
to give other threads a chance.

Use get_conf_with_default instead of get_conf because fsid is a known
ceph configuration option. It allows overriding via CEPH_ARGS which is
convenient for testing. Only options that are not found in config_opts.h
are fetch via get_conf.
