Rather than setting the compiler to cc on all platforms by default,
use the Autoconf default unless the specific compiler might matter.
Conservatively set the compiler to cc for all non-Linux, non-BSD
operating systems that previously didn't explicitly set it. Fix a
few places on Linux where the compiler was set to gcc explicitly
rather than using the Autoconf result.
Don't bother setting the Linux i386 compiler to gcc -pipe. The compile
performance difference isn't enough to bother with the special
exception, and we don't do this for other Linux systems.
With this change, setting CC at Autoconf time will correctly set the
compiler per the user's preferences unless they're on an operating
system where we care about having a particular compiler for kernel
purposes. This can be relaxed further in the future, particularly if
the kernel compiler is broken out to a separate setting.

The SMB redirector will permit two processes to open the
pioctl file at the same time without giving SMB server an
opportunity to say 'no'. As a result multiple reads and writes
on the allocated smb_fid->ioctl can play havoc with the pioctl
state. Since afsd_service doesn't know the writes and reads
are coming from separate requests there is nothing it can do
to prevent incorrect data going to the wrong process. However,
it can (and should) protect itself when the state becomes invalid.
Two prevention methods are applied:
1. add an additional state flag that explicitly indicates
when the ioctl is in the dataout state
2. validate the length of data in the ioctl input or
output buffers before copying it. If the length
becomes negative, return a CM_ERROR_INVAL error.
In addition, when the invalid state results in a failure to
to find a matching pioctl function do not return CM_ERROR_BADOP.
CM_ERROR_BADOP can only be returned if the SMB operation is not
supported. Returning it in response to a ReadFile request will
cause the SMB client to drop the connection.
Finally, fix smb_FindFID to prevent the same 'fid' from being
used for more than one open file.

The Windows pioctl implementation makes an incorrect assumption.
It is not true that every CreateFile() operation results in a
SMB NTCreateX operation being delivered to SMB Server. The SMB
client can combine open requests from multiple processes or threads
onto a single SMB file descriptor and locally manage the operations.
This is a problem for pioctls since the Transceive operation requires
that a WriteFile/ReadFile combination must belong to the same request.
Prior to this change simultaneous pioctl operations would be
combined and the individual reads and writes could overlap resulting
in responses going to the wrong requestor and end of file errors
being received by the others.
Due to lack of data validation in fs.c, ktc_nt.c, symlink.c,
etc random crashes are produced.
This change alters the sharing mode under which the pioctl file is
opened. Instead of FILE_SHARE_READ | FILE_SHARE_WRITE, only
FILE_SHARE_READ is specified to CreateFile(). This ensures that
the CreateFile will fail with a sharing violation if the pioctl
file was previously opened for writing.
A sharing violation check is provided and the CreateFile is retried
indefinitely until the open succeeds or the error is not a sharing
violation.

Right now, when the fileserver shuts down, it tries to cancel any
demand-salvages in progress. This causes the fileserver to hang, since
during shutdown, the salvageserver may already be gone. This avoids
cancelling in-progress salvages, and allows salvages to continue after
the fileserver has shut down.
To do this, the salvageserver now closes SALVSYNC sockets in spawned
children, so the children don't get SALVSYNC requests directed at them,
since they can't handle them. The salvageserver also now periodically
scans for logs of salvaging children that have terminated, and
incorporates them into SalsrvLog, just like it does for it's own
children. The salvageserver children that actually perform salvages now
also set the inUse volume header field to their programType, so the
