e820c0abc8 Update spelling "mbed TLS" to "Mbed TLS"
The official spelling of the trade mark changed from all-lowercase "mbed"
to normal proper noun capitalization "Mbed" a few years ago. We've been
using the new spelling in new text but still have the old spelling in a
lot of text. This commit updates most occurrences of "mbed TLS":

```
sed -i -e 's/mbed TLS/Mbed TLS/g' $(git ls-files ':!ChangeLog' ':!tests/data_files/**' ':!tests/suites/*.data' ':!programs/x509/*' ':!configs/tfm*')
```

Justification for the omissions:

* `ChangeLog`: historical text.
* `test/data_files/**`, `tests/suites/*.data`, `programs/x509/*`: many
  occurrences are significant names in certificates and such. Changing
  the spelling would invalidate many signatures and tests.
* `configs/tfm*`: this is an imported file. We'll follow the upstream
  updates.

0b62b7a21f Allow turning off re-generation of files with make
In make builds, when GEN_FILES is false (empty), don't try to re-generate
configuration-independent source files, regardless of whether they seem
out of date. This is useful, for example, if you have a source tree where
`make generated_files` has already run and file timestamps reflect the
time the files were copied or extracted, and you are now in an environment
that lacks some of the necessary tools to re-generate the files.

6d14c2b858 Remove dead code
Do explain why we don't test a smaller buffer in addition to testing the
nominal size and a larger buffer.

c9187c5866 New test suite for the low-level hash interface
Some basic test coverage for now:

* Nominal operation.
* Larger output buffer.
* Clone an operation and use it after the original operation stops.

Generate test data automatically. For the time being, only do that for
hashes that Python supports natively. Supporting all algorithms is future
work.

44243e11ff Remove obsolete header inclusions
Since 3.0.0, mbedtls_config.h (formerly config.h) no longer needs to include
config_psa.h or check_config.h: build_info.h takes care of that.

ead1766b5f Fix PBKDF2 with empty salt segment on platforms where malloc(0)=NULL
"Fix PBKDF2 with empty salt on platforms where malloc(0)=NULL" took care of
making an empty salt work. But it didn't fix the case of an empty salt
segment followed by a non-empty salt segment, which still invoked memcpy
with a potentially null pointer as the source. This commit fixes that case,
and also simplifies the logic in the function a little.

Test data obtained with:
```
pip3 install cryptodome
python3 -c 'import sys; from Crypto.Hash import SHA256; from Crypto.Protocol.KDF import PBKDF2; cost = int(sys.argv[1], 0); salt = bytes.fromhex(sys.argv[2]); password = bytes.fromhex(sys.argv[3]); n = int(sys.argv[4], 0); print(PBKDF2(password=password, salt=salt, dkLen=n, count=cost, hmac_hash_module=SHA256).hex())' 1 "" "706173737764" 64
```

cfae6a1ae9 Fix incorrect detection of HardwareModuleName
The hardware module name otherName SAN contains 2 OIDs:

 OtherName ::= SEQUENCE {
      type-id    OBJECT IDENTIFIER,
      value      [0] EXPLICIT ANY DEFINED BY type-id }

 HardwareModuleName ::= SEQUENCE {
                           hwType OBJECT IDENTIFIER,
                           hwSerialNum OCTET STRING }

The first, type-id, is the one that identifies the otherName as a
HardwareModuleName. The second, hwType, identifies the type of hardware.

This change fixes 2 issues:

1. We were erroneously trying to identify HardwareModuleNames by looking
at hwType, not type-id.
2. We accidentally inverted the check so that we were checking that
hwType did NOT match HardwareModuleName.

This fix ensures that type-id is correctly checked to make sure that it
matches the OID for HardwareModuleName.
