7975fae6bd Move to separately compiled PSA test driver library
This commit removes the test_psa_crypto_config_basic
all.sh component that can no longer work without
adapting it to the separately compiled test driver
library. This component is replaced by several
components in the following commits to test various
type of acceleration independently.

f303c0ddeb Fix several bugs with multiline comments
Empty the current line if it's entirely inside a comment.

Don't incorrectly end a block comment at the second line if it doesn't
contain `*/`.

Recognize `/*` to start a multiline comment even if it isn't at the start of
the line.

When stripping off comments, consistently strip off `/*` and `*/`.

9b2fa72a43 Simplify some regex definitions
Use '|'.join([comma-separated list]) rather than r'...|' r'...|'. This way
there's less risk of forgetting a '|'. Pylint will yell if we forget a comma
between list elements.

Use match rather than search + mandatory start anchor for EXCLUSION_LINES.

152de23518 Lift some code out of parse_identifiers
Make parse_identifiers less complex. Pylint was complaining that it had too
many local variables, and it had a point.

* Lift the constants identifier_regex and exclusion_lines to class
  constants (renamed to uppercase because they're constants).
* Lift the per-file loop into a new function parse_identifiers_in_file.

No intended behavior change.

c8794202e6 Fix comment parsing
Fix cases like
```
/*short comment*/ /*long
 comment */
int mbedtls_foo;
```
where the previous code thought that the second line started outside of a
comment and ended inside of a comment.

I believe that the new code strips comments correctly. It also strips string
literals, just in case.

Fixes #5191.

89458d1420 More robust handling of excluded files
Don't try to enumerate excluded files. List included files, and remove names
from the list if they match an excluded-file pattern.

This resolves the problem that the script could get into an infinite loop
due to the use of recursive globbing. Unfortunately, Python's recursive
globs follows symbolic links to directories, which leads to an infinite loop
if a symbolic link points to an ancestor of the directory that contains it.

fc1e9ffcb2 Use Abstract Base Classes to ensure Problem is not instantiated
- Problem() is a parent abstract class that should only be used for
  subclassing.
- With the help of ABC, implement abstract methods that force
  subclasses to implement quiet and verbose outputs.
- The repeated logic of "if self.quiet" is consolidated in Problem.

704b0f77e1 Use .span() for positions, and separate line_no argument in Match
This reverts a previous change where line_no was removed and put into
a triple tuple. It was discovered that re.Match.span() conveniently
returns (start, end), so separating line_no again makes the code cleaner.
The legibility of the code heavily outweighs the issues pointed out by
Pylint (hence disabled).

8e9a219310 Improve ease of specifying which files to look in (check_names)
- Instead of os.path.join, use glob patterns (supports Windows too)
- Instead of creating the lists beforehand (which adds messiness), pass glob
  expessions to functions and let them memoise it.
- Add support for excluding based on glob patterns, which isn't used now but
  could come in handy.

977e07f5c8 Use glob in get_files(), call setup_logger on init
glob is more flexible and simplifies the function arguments drastically.
It is also much more intuitive to extend in the future when the filepaths
need to be extended or changed.

setup_logger had to be called as the first thing after instantiation, so
this commit simplify makes it automatic.

Several clarification comments are added too.
