Use StrSafe string manipulation functions in place of most
instances of strcpy, strcat, sprintf, etc. With the use
of StringCbCopy, StringCbCat, StringCbPrintf, etc. there
is no longer a need to manually assign a NUL to the end
of a C string buffer as was required with strncpy or
strncat.
There is one strcpy instance remaining due to the inability
to know what the length of the destination buffer. The API
needs to be altered to make the destlen available and that is
not an appropriate change for this patchset. A deprecated
warning is a reminder to revisit this in the future.
Several int to unsigned int type changes to avoid signed

Change I03ecf6302436c35fec705cd6c84a40b7cdbf6f97 allowed non-fileserver
programs to schedule salvages via FSSYNC, making the FSSYNC call
directly in VRequestSalvage_r. This isn't as safe as making the call in
VScheduleSalvage_r (as is done when the fileserver schedules a salvage
via SALVSYNC), since we may not have relinquished all of our handles and
such for the volume by the time the salvager starts.
So instead, make this path a bit more like the fileserver, and make
non-fileserver programs actually make the FSSYNC call in
VScheduleSalvage_r. Consequently, make VScheduleSalvage_r conditionally
hit FSSYNC or SALVSYNC. Add a VCheckSalvage to attach2 failures, so
non-fileserver salvage requests actually get scheduled.
Also, reorganize the attach2 error handling a bit to make this a bit
easier.

to take a timeout in milliseconds, we must correct for the (sometimes)
different units (currently HZ defaults to 1000). We prefer
to multiply the timeout by HZ before dividing by 1000 so as to
not lose precision; overflow is assumed to be unlikely.

The keyring destructor on Linux was only destroying the first

where each PAG contains tokens for multiple cells, this led to us
leaking unixuser structures, and eventually grinding to a hault due
to the length of the resulting hash chains (and some horrific
O(n-squared) performance in the PAG statistics code).
Add a utility function for the keyring destruction function to call
which will mark as deleted all unixuser structures for a particular
PAG, and use it.

that everything in the initial commit to that tree was available in all

Secondly, the new readpage code uses zero_user_segments, which has only
been available in the mainline kernel since 2.6.25 (RHEL5 appears to have
a backport)
Implement local wrappers for both of these functions when configure can't
find them in the kernel we're building for.
These functions have been created independently of the Linux tree.
