d362d0bf86 Tweak spacing in Visual Studio files
Tweak the code to be slightly simpler and closer to mbedtls. This
changes non-significant whitespace in the generated files.

7156d8cda9 Don't hard-code include paths in templates
generate_visualc_files.pl has a list of directories that it pulls
headers from, so it knows what directories to put on the include path.
Make it inject the include path into the output files, rather than
hard-coding the include paths in template files.

A similar change (but with different code) was made in Mbed TLS in
commit b78cf2b261
"Adjust visual studio file generation to always use the crypto submodule".

No semantic change: this commit does not change the generated files.

b41f88f47a Simplify the code around the call to gen_main_file
There's no need to keep the directory lists separated until the last
minute.

No semantic change. The generated files change slightly because there
was one directory list where slashes were not changed to backslashes
like in the other five. This does not affect their semantics.

13fac98aca Generalize everest support to generic 3rdparty support
Other third-party components can now be added by just adding lines to
the definitions of @thirdparty_header_dirs and
@thirdparty_source_dirs.

No semantic change. The output does not change at all.

2579675935 Merge remote-tracking branch 'upstream-public/development' into development
Files deleted by us: keep them deleted.

```
git rm $(git status -s | sed -n 's/^DU //p')
```

Individual files with conflicts:

* `README.md`: keep the crypto version.
* `doxygen/input/doc_mainpage.h`: keep the crypto version (with an obsolete Mbed Crypto version number).
* `include/mbedtls/error.h`:
    * `ERROR`: similar additions made through parallel commits, with only whitespace differences. Align with the tls version.
* `library/CMakeLists.txt`: keep the crypto version.
* `library/Makefile`: keep the crypto version.
* `scripts/generate_errors.pl`: keep the crypto version (the relevant changes were made through parallel commits).
* `tests/scripts/check-test-cases.py`:
    * `Results`: keep the crypto version, which has both the new argument to the constructor (added in crypto only) and the class docstring (added through parallel commits).
* `tests/suites/helpers.function`:
    * `ARRAY_LENGTH`, `ASSERT_ALLOC`: additions in the same location. Keep both, in indifferent order.
* `tests/suites/target_test.function`:
    * `receive_uint32`: keep the crypto version which has an additional bug fix. The tls changes made in tls are irrelevant after this bug fix.
* `visualc/VS2010/mbedTLS.vcxproj`: run `scripts/generate_visualc_files.pl`.

Review of non-conflicting changes:

* `all.sh`: 1 change.
    * zlib test components: don't add them.
* `include/CMakeLists.txt`: 1 change.
    * `target_include_directories`: doesn't work as is (different target name). Don't take the change.
* All other non-conflicting changes: take them.

f65ed6f254 Change key types to a 16-bit encoding
All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.

Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.

Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.

Reorder psa_core_key_attributes_t to avoid padding.

df587ee6d6 Remove duplicate include statement
Now that the Error module has error codes as well and is processed by
the generate_errors script like any other module, we don't need to
include the header manually.

2d20567122 Add two error codes to the Error module
One of the error codes was already reserved, this commit just makes it
explicit. The other one is a new error code for initializing return
values in the library: `MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED` should
not be returned by the library. If it is returned, then it is surely a
bug in the library or somebody is tampering with the device.

49af2d3a4f Support non-ASCII characters in headers
Filter out non-ASCII characters in automatically processed headers.

Do this in a way that minimizes the code change: keep manipulating
strings, but strip off non-ASCII characters when reading lines, which
should only remove characters in comments that we don't parse anyway.

80a607171a config.pl full: exclude MBEDTLS_ENTROPY_FORCE_SHA256
This is a variant toggle, not an extra feature, so it should be tested
separately.

We test most of the effect of MBEDTLS_ENTROPY_FORCE_SHA256 (namely,
using SHA-256 in the entropy module) when we test the library with the
SHA512 module disabled (which we do at least via depends-hashes.pl).
This commit removes testing of the MBEDTLS_ENTROPY_FORCE_SHA256 option
itself, which should be added separately.

24600e8290 Disable memory_buffer_alloc in the full config
Enabling MBEDTLS_MEMORY_BUFFER_ALLOC_C module together with
MBEDTLS_PLATFORM_MEMORY causes the library to use its own malloc
replacement. This makes memory management analyzers such as ASan
largely ineffective. We now test MBEDTLS_MEMORY_BUFFER_ALLOC_C
separately. Disable it in the "full" config.

This mirrors a change that was made in Mbed TLS on config.pl and had
not been ported to Mbed Crypto yet.

With this commit, config.py is aligned in Mbed Crypto and Mbed TLS.

261742bd59 Fix config.py output when a symbol has acquired or lost a value
Normally a valueless symbol remains valueless and a symbol with a
value keeps having one. But just in case a symbol does get changed
from valueless to having a value, make sure there's a space between
the symbol and the value. And if a symbol gets changed from having a
value to valueless, strip trailing whitespace.

Add corresponding tests.

Also fix the case of a valueless symbol added with the set method,
which would have resulted in attempting to use None as a string. This
only happened with the Python API, not with the command line API.

812f185bc8 Also search config.h near the script
By default, this script looks for include/mbedtls/config.h relative to
the current directory. This allows running config.py from outside the
build tree.

To support out-of-tree builds where config.h and config.py are in the
source tree and the current directory is in the build tree, also try
DIRECTORY_CONTAINING_SCRIPT/../include/mbedtls/config.h, and the
equivalent with symbolic links traversed.

They're easier to maintain that way. The old lists were partly

39bd5e7f9e Mbed TLS configuration file manipulation library and tool
This is meant to be a drop-in replacement for config.pl which can

but not the other built-in configurations.
