synctask: implement setuid-like SYNCTASK_SETID()

synctasks can now call SYNCTASK_SETID(uid,gid) to set the effective
uid/gid of the frame with which the FOP will be performed.

Once called, the uid/gid is set either till the end of the synctask
or till the next call of SYNCTASK_SETID()

glusterfsd: Remove 'top {read,write}-perf' thread

'volume top {read,write}-perf' were performed in a different thread on the brick
process, to prevent them from blocking the main polling thread. This was
essential earlier when the rpc actor functions were run in the epoll thread. Now
rpc actors can be launched on their own threads with the introduction of
synctask support for rpcsvc. The brick-op actors are now launched using this
feature, which makes the need for '{read,write}-perf' to be performed in a new
thread.

rpc: bring in root-squashing behavior in rpc

* requests coming in as root are converted to nfsnobody

* with open-behind some acl checks wont happen and nfsnobody
  can read the file "whose owner is root and other users do not
  have permission to read the file". This is becasue open-behind
  does not send the open to the brick and sends success to the
  application, thus the acl related tests on the file wont happen
  which would have prevented the file from being opened.

features: add a directory-protection translator

This is useful to find all calls that remove a file from the protected
directory, including renames and internal calls.  Such calls will cause
a stack trace to be logged.  There's a filter script to add the needed
translators, and then the new functionality can be invoked with one of
the following commands.

	setfattr -n trusted.glusterfs.protect -v log $dir
	setfattr -n trusted.glusterfs.protect -v reject $dir
	setfattr -n trusted.glusterfs.protect -v anything_else $dir

The first logs calls, but still allows them.  The second rejects them
with EPERM.  The third turns off protection for that directory.

LinuxRPM/Makefile: fix backquote which was triggering recursive make

The following Makefile snippet:

--snip--
all:
	@echo "To build RPMS run `make glusterrpms`"
--snip--

was using `backquotes` in the string, and thereby triggering a nested
make on "glusterrpms" target implicitly as part of 'make all', thus
defeating the intention.

So use single quotes instead of backquotes.

It is unexplained why this nested 'make glusterrpms' was not called on
the build server during regression test.
