Rx: Do not hold call lock across memcpy in rx_ReadProc/rx_WriteProc

1.4.x does not hold the call lock across memcpy operations in
rx_ReadProc, rx_ReadProc32, rx_WriteProc, rx_WriteProc32.  The
claim is that the call curpos, curlen, and nLeft fields which
refer to the current packet being processed will not be touched
by any other thread.  Therefore it is safe to drop the call lock
to permit another thread to add packets to the call while the memcpy
is performed in parallel.

This patchset continues to hold the call lock longer than the
original implementation but does drop it for the length of time
it takes to copy data from the packet buffer to the application
buffer.

Linux: normalize error return for emulated syscalls

pagsh and other code expect setpag() and pioctl() to behave like
a regular syscall or pioctl, that is to return -1 on error, with
errno set to the specific error code.
On Linux, the underlying emulation does a straight return of any
error code it gets from the ioctl, and errors are not properly
caught by the callers.

As an example, pagsh won't detect an error from setpag such as
exceeding a keyring quota limit.  With this patch, the user
will see this:

$ pagsh
setpag: Disk quota exceeded
sh-4.1$

The code in proc_afs_syscall is modified to set errno to the error
code and to set errorcode to -1 in case of error.

proc_afs_sycall is reindented while we're changing code there.

Windows: Improve SMB detection of Local System account

Depending on the authentication method, the smb session authenticated
name for the "local system" account may be the nul string.  In this
case it is impossible to use the name to determine if the authenticated
entity is the "local system" account as required by smb_SetToken.
To work around this problem, smb_AuthenticateUserExt() will now obtain
the Security Identifier (SID) for the authenticated account.  The string
representation of the SID will be used in place of the name by
smb_ReceiveV3SessionSetupX() when constructing the smb_user_t object.
A new flag, SMB_USERNAMEFLAG_SID, indicates when the name is in fact
a SID.

smb_userIsLocalSystem() checks for the SMB_USERNAMEFLAG_SID flag and
performs a SID comparison when it is set.

smb_SetToken() will accept either MACHINE\user or a SID string as
the smbname.  It will obtain the SID if possible and create a SID-based
smb_user_t.

It is possible that a SYSTEM service will use an anonymous (S-1-5-7)
SMB connection.  In that case, we also check the RPC Impersonation
SID to see if it is SYSTEM.  If so, the RPC identity supercedes the
SMB identity for SetToken.

smb_IoctlRead, smb_IoctlV3Read and smb_IoctlRawRead are now all
consistent with regards to name processing.

Fixed a couple of comments as well.

Windows: Modify signature of buf_CleanAsync and buf_CleanAsyncLocked

The buf_CleanAsync() and buf_CleanAsyncLocked() signature does
not include a cm_scache_t pointer even though buf_CleanAsyncLocked()
needs a pointer to the matching cm_scache_t object.  There are
some calls when the cm_scache_t object is already known.  For those
cases it is more efficient to avoid the additional lookup especially
when buf_CleanAsync*() is being called on every buffer associated
with the cm_scache_t object.

At the same time add a flags field and a constant
CM_BUF_WRITE_SCP_LOCKED to permit the lock state of the cm_scache_t
to be passed in.

Finally, fix up the usage in buf_FlushCleanPages() which gains
the most from these changes.

Fixes for signed char architectures

"char" is unsigned on s390x, which causes a few warnings where we
test for negative values.

Add a signed modifier in a few cases, and in vos.c replace with an
int to match a similar section of code in the same file.

Mostly a warning fix, but in one case the variable could be used
to return a -1 error value, so it may have caused an actual bug.

Linux: avoid oops in memcpy_toiovec

With ADAPT_PMTU enabled, kernel_recvmsg can be called to receive
errors.  The call is made with no iovec supplied (we pass a NULL
pointer), but with a size of 256.  In the kernel, the memcpy_toiovec
function tests for size > 0, and proceeds to check iovec->iov_len,
which causes an oops.  Fix by setting the size to 0.
