The signature and naming of the Montgomrey initialisation function in
development and in the LTS was different. Align them for easier
readability and maintenance.

So far we needed it only locally here, but we will need calculating RR
for safe unblinding in RSA as well.

mbedtls_ssl_cache_get() and mbedtls_ssl_cache_set() returned 1 on many error
conditions. Change this to returning a negative MBEDTLS_ERR_xxx error code.
Completeness: after this commit, there are no longer any occurrences of
`return 1` or `ret = 1`.

With stream ciphers, add a check that there's enough room to read a MAC in
the record. Without this check, subtracting the MAC length from the data
length resulted in an integer underflow, causing the MAC calculation to try
reading (SIZE_MAX + 1 - maclen) bytes of input, which is a buffer overread.

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.

* Prevent pkcs12_pbe encryption when PKCS7 padding has been
disabled since this not part of the specs.
* Allow decryption when PKCS7 padding is disabled for legacy
reasons, However, invalid padding is not checked.
* Document new behaviour, known limitations and possible
security concerns.
* Add tests to check these scenarios. Test data has been
generated by the below code using OpenSSL as a reference:
int main()

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.

When parsing a subject alternative name of type otherName, retain the
type-id field of the otherName. Previously this was not copied to the
mbedtls_x509_san_other_name struct when it should have been.
