With the removal of MBEDTLS_MEMORY_BUFFER_ALLOC_C from the
full config, there are no tests for it remaining in all.sh.
This commit adds a build as well as runs of `make test` and
`ssl-opt.sh` with MBEDTLS_MEMORY_BUFFER_ALLOC_C enabled to all.sh.
Previously, numerous all.sh tests manually disabled the buffer allocator
or memory backtracting after setting a full config as the starting point.
With the removal of MBEDTLS_MEMORY_BACKTRACE and MBEDTLS_MEMORY_BUFFER_ALLOC_C
from full configs, this is no longer necessary.

For unit tests and sample programs, CFLAGS=-m32 is enough to get a
32-bit build, because these programs are all compiled directly
from *.c to the executable in one shot. But with makefile rules that
first build object files and then link them, LDFLAGS=-m32 is also
needed.
Due to the way the current PK API works, it may have not been clear
for the library clients, how big output buffers they should pass
to the signing functions. Depending on the key type they depend on
MPI or EC specific compile-time constants.
Inside the library, there were places, where it was assumed that
the MPI size will always be enough, even for ECDSA signatures.
However, for very small sizes of the MBEDTLS_MPI_MAX_SIZE and
sufficiently large key, the EC signature could exceed the MPI size
and cause a stack overflow.
This test establishes both conditions -- small MPI size and the use
of a long ECDSA key -- and attempts to sign an arbitrary file.
This can cause a stack overvlow if the signature buffers are not
big enough, therefore the test is performed for an ASan build.
When running make with parallelization, running both "clean" and "lib"
with a single make invocation can lead to each target building in
parallel. It's bad if lib is partially done building something, and then
clean deletes what was built. This can lead to errors later on in the
lib target.

To avoid this sort of trouble, always invoke clean by itself without
other targets throughout the library. Don't run clean in parallel with
other rules. The only place where clean was run in parallel with other
targets was in list-symbols.sh.
We've observed that sometimes check-names.sh exits unexpectedly with
status 2 and no error message. The failure is not reproducible. This
commits makes the script print a trace if it exits unexpectedly.
When doing ABI/API checking, its useful to have a list of all the
identifiers that are defined in the internal header files, as we
do not promise compatibility for them. This option allows for a
simple method of getting them for use with the ABI checking script.
Run ssl-opt.sh on x86_32 with ASan. This may detect bugs that only
show up on 32-bit platforms, for example due to size_t overflow.
For this component, turn off some memory management features that are
not useful, potentially slow, and may reduce ASan's effectiveness at
catching buffer overflows.

Line issue trackers are conceptually a subclass of file issue
trackers: they're file issue trackers where issues arise from checking
each line independently. So make it an actual subclass.
Pylint pointed out the design smell: there was an abstract method that
wasn't always overridden in concrete child classes.
Wildcard patterns now work with command line COMPONENT arguments
without --except as well as with. You can now run e.g.
`all.sh "check_*` to run all the sanity checks.
After backing up and restoring config.h, `git diff-files` may report
it as potentially-changed because it isn't sure whether the index is
up to date. To avoid this, make sure that the git index is up-to-date.
This fixes the warning about changed config.h that you might get when
you run all.sh twice in succession, yet if you run `git status` or
`git diff` everything seems up to date and you no longer get the
warning because these git commands update the index.

Only look for armcc if component_build_armcc or component_build_yotta
is to be executed, instead of requiring the option --no-armcc.
You can still pass --no-armcc, but it's no longer required when
listing components to run. With no list of components or an exclude
list on the command line, --no-armcc is equivalent to having
build_armcc in the exclude list.
Omit the yotta pre-checks if the build_yotta component is not going to
be executed. This makes --no-yotta equivalent to specifying a list of
components to run that doesn't include build_yotta.
Add a conditional execution facility: if a function support_xxx exists
and returns false then component_xxx is not executed (except when the
command line lists an explicit set of components to execute).
Use this facility for the 64-bit-specific or amd64-specific components.
