mds: preserve subtree bounds until slave commit

When replaying an operation that rename a directory inode to non-auth subtree,
if the inode has subtree bounds, we should prevent them from being trimmed
until slave commit.

This patch also fixes a bug in ESlaveUpdate::replay(). EMetaBlob::replay()
should be called before MDCache::finish_uncommitted_slave_update().

mds: process finished contexts in batch

If there are several unstable locks in an inode, current Locker::eval(CInode*,)
processes each lock's finished contexts seperately. This may cause very deep
call stack if finished contexts also call Locker::eval() on the same inode.
An extreme example is:

Locker::eval() wakes an open request(). Server::handle_client_open() starts
a log entry, then call Locker::issue_new_caps(). Locker::issue_new_caps()
calls Locker::eval() and wakes another request. The later request also tries
starting a log entry.

mds: fix MDCache::adjust_bounded_subtree_auth()

There are cases that need both create new bound and swallow intervening
subtree. For example: A MDS exports subtree A with bound B and imports
subtree B with bound C at the same time. The MDS crashes, exporting
subtree A fails, but importing subtree B succeed. During recovery, the
MDS may create new bound C and swallow subtree B.

rgw: with CORS support

With CORS test cases

1. Added license headers to the cors files
2. SIWFT POST metadata for cors will replace the old cors configuration
3. Fixed a buf in rgw_cors_swift.h

With Yehuda's review comments along with some fixes;
1. If the origin is allowed only for https, we should not approve the same host for http requests
2. Accounted for hostname situtation like www.www.org, or www.wowwww.com or www.*
3. Replaced atoi with strtol
4. Have a centralized place for parsing host names, hence avoiding duplicates

Checked certain senarios with amazon S3 and made changes accordingly

With some fixes in rgw_cors.cc and str_list.cc

Removing the whitespace auto-append to the delimiters in get_str_list(), added white spaces delimiters in is_string_in_set()
rgw: cors, style fixes, other fixes

Modified the type of 'a' to unsigned long and used ULONG_MAX and strtol in rgw_cors_swift.h

On a 64-bit arch, we still want to make sure it's a 32-bit value.  Gcc is
