New abstractions to access ssl->hostname:
mbedtls_ssl_has_set_hostname_been_called() (only implemented approximatively
for now), mbedtls_ssl_get_hostname_pointer(), mbedtls_ssl_free_hostname().
Only access ssl->hostname directly in these functions and in
mbedtls_ssl_set_hostname().
Use these abstractions to access the hostname with the opportunity for
extra checks in mbedtls_ssl_verify_certificate().
No behavior change except for a new log message.

When calculating a result to go into an mbedtls_ms_time_t, make sure
that arithmetic is performed at the final size to prevent overflow.

RNG check is added in ssl_conf_check when calling mbedtls_ssl_setup,
so there is no need to check it again.

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.

A few functions were changed from returning void to returning int three
commits ago. Make sure their callers check the return values.
This commits was basically a matter of declaring newly-int-returning
functions MBEDTLS_CHECK_RETURN_CRITICAL and then fixing the resulting
warnings. A few functions had to be made int in the process; they were
applied the same process as well.
