Some tests will need variables, and so we need a mock implementation of
the various calls relating to them.
This patch adds implementations for the EFI Runtime Services calls
GetVariable(), SetVariable(), GetNextVariableName(), and
QueryVariableInfo(). Additionally, it enforces tunable limits on
storage for variables, and (with only a little work) the limits can be
different for SetVariable() vs what is returned by QueryVariableInfo().
That is, it can lie to you like real systems do.

This adds compile_commands.json (used by https://github.com/neoclide/coc.nvim)
and clangd's .cache/ directory to .gitignore.

On some versions of binutils[0], including binutils-2.23.52.0.1-55.el7,
do not correctly initialize the data when computing the PE optional
header checksum. Unfortunately, this means that any time you get a
build that reproduces correctly using the version of objcopy from those
versions, it's just a matter of luck.
This patch introduces a new utility program, post-process-pe, which does
some basic validation of the resulting binaries, and if necessary,
performs some minor repairs:
- sets the timestamp to 0
- this was previously done with dd using constant offsets that aren't
really safe.
- re-computes the checksum.
[0] I suspect, but have not yet fully verified, that this is
accidentally fixed by the following upstream binutils commit:

Lose some COFF/PE static vars, and peicode.h constify
This patch tidies some COFF and PE code that unnecessarily used static
variables to communicate between functions.
v2 - MAP_PRIVATE was totally wrong...

If the file Make.local exists, use it as a source of local build
configuration by including it in Make.defaults.
(cherry picked from commit 57e38a1ebf73 in the shim-15.2 branch)

This does a couple of straightforward tests on our CSV parser, and then
for good measure it does two with random data - one that's just random
data, one that's had all the zeros changed to nonzero values.
Note that building and running this test does not quite work yet /on
this branch/. In order to do that, we need some cleanups and
reorganizing that I don't want to push just yet, which can be found on
https://github.com/rhboot/shim/tree/test-reorg

This adds a couple of make targets to do unit tests that are linked to
libc:
test-FOO : builds and runs test-FOO for any test-FOO.c
test : builds and runs all test-FOO tests
Note that building and running this test does not quite work yet /on
this branch/. In order to do that, we need some cleanups and
reorganizing that I don't want to push just yet, which can be found on

This adds stuff that only ever gets made as an artifact of building
(though build*/ generally doesn't, as of this commit.)

This had gotten weird in a couple of ways. Easy to fix.

Add .cer/.crt/.esl to .gitignore
But .cer and .crt were added independently in another commit since then.

In cases where we accept vendor shim binaries with additional patches,
it may become necessary to identify those builds with additional SBAT
data. When we consider such patches, we should be proactive in asking
vendors to include that data in the .sbat sections of their trusted EFI
binaries.
This patch adds any data in data/sbat.*.csv (after a quick sanitizing
pass) after data/sbat.csv in the .sbat section, so that no changes to
the upstream data/sbat.csv are ever required.
