The code is splattered with a mix of
sizeof foo
sizeof (foo)
sizeof(foo)
Standardize on sizeof(foo) and add a syntax check rule to
enforce it

When trying to use any SASL authentication for TCP sockets by
setting auth_tls = "sasl" in libvirtd.conf on server side, the
client will hang because of the sasl session relocking other than
dropping the lock when exiting virNetSASLSessionExtKeySize()
* src/rpc/virnetsaslcontext.c: virNetSASLSessionExtKeySize drop the
lock on exit
Detected by Coverity. We want to compare the result of fnmatch 'rv',
not our pre-set return value 'ret'.
* src/rpc/virnetsaslcontext.c (virNetSASLContextCheckIdentity):
Check correct variable.
On RHEL 5, with gcc 4.1.2:
rpc/virnetsaslcontext.c: In function 'virNetSASLSessionUpdateBufSize':
rpc/virnetsaslcontext.c:396: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
* src/rpc/virnetsaslcontext.c (virNetSASLSessionUpdateBufSize):
Use a union to work around gcc warning.
The virNetSASLContext, virNetSASLSession, virNetTLSContext and
virNetTLSSession classes previously relied in their owners
(virNetClient / virNetServer / virNetServerClient) to provide
locking protection for concurrent usage. When virNetSocket
gained its own locking code, this invalidated the implicit
safety the SASL/TLS modules relied on. Thus we need to give
them all explicit locking of their own via new mutexes.
* src/rpc/virnetsaslcontext.c, src/rpc/virnettlscontext.c: Add
a mutex per object
This provides two modules for handling SASL
* virNetSASLContext provides the process-wide state, currently
just a whitelist of usernames on the server and a one time
library init call
* virNetTLSSession provides the per-connection state, ie the
SASL session itself. This also include APIs for providing
data encryption/decryption once the session is established
* src/Makefile.am: Add to libvirt-net-rpc.la
* src/rpc/virnetsaslcontext.c, src/rpc/virnetsaslcontext.h: Generic
SASL handling code
