diff: Report I/O errors in Stone algorithm

In the legacy Stone algorithm, we do a first pass over the files to
check if they're identical before we start diffing them.  That code
would correctly set the exit status if an I/O error was encountered,
but would not emit an error message.  Do so.

diff: Don't compare a file or directory to itself

While here, stop abusing struct dirent for something we don't even need
to store.

diff: Fix pagination leak

* Drop an unnecessary variable and rename pidfd to procd.

* Rewinding stdout serves no purpose, so stop doing it.

* Don't bother freeing memory or setting the global status right
  before erroring out.

* Error out if dup(2) or dup2(2) fail.

* In the unlikely case that our pipe is equal to stdout, we need to
  record that information so we don't close it when cleaning up.

* Don't bother closing a descriptor before dup2(2)ing to it.

* Don't forget to close the the process descriptor after reaping the
  child process.

diff: Add test case for pagination resource leak

The pagination code leaks either processes or descriptors or both,
depending on the exact version of the code you have.  Add a test case
which exercises this leak to facilitate fixing it.

diff: Fix integer overflows in Stone algorithm

Fix integer overflows that may occur when the context window is very
large and add tests to exercise those conditions.

iwx: migrate to new net80211 encryption key API

Migrate to the new encryption key API rather than poking at the
key struct directly.

Locally tested:

 * STA mode - iwx0: <Wi-Fi 6 AX210> mem 0x84c00000-0x84c03fff at device 0.0 on pci4

net80211: clean up time comparison in HT code

There's at least one place where the time comparison is wrong, leading
to some bad beahaviour around deciding to try and establish/reestablish
AMPDU TX sessions.

Start addressing these!
