It is sufficient to check for the strongest limit only. Using a smaller
type ensures there is no overflow (assuming size_t is at least 32 bits).

1. The functions mbedtls_high_level_strerr and mbedtls_low_level_strerr
accept any error code and extract the high-level and low-level parts
respectively.
2. Documentation updates.

Use "no_deprecated" both in the name of the configuration and in the
name of all.sh components, rather than a mixture of "no_deprecated"
and "non_deprecated".
Make all.sh component names more consistent.

Every boolean (defined/undefined) symbol is a "variant toggle" in some
sense, even enabling a module with MBEDTLS_xxx_C. What matters is
whether the symbol influences some other part of the system in such a
way that we need to run tests separately with and without it being
defined.

build_deprecated combined the testing of deprecated features, and
testing of the build without deprecated features. Also, it violated the
component naming convention by being called build_xxx but running tests.
Replace it by:
* test_default_no_deprecated: check that you can remove deprecated
features from the default build.
* test_full_no_deprecated: check that the library builds when deprecated
features are disabled (and incidentally that the tests run).
* test_no_deprecated_warning: check that there are no warnings when
deprecated features are disabled and MBEDTLS_DEPRECATED_WARNING
is enabled.
* test_deprecated: test the deprecated features.

It's deprecated, but not otherwise counter-indicated for the full
config: it doesn't conflict with anything and enabling it doesn't make
testing harder (especially since it defaults off in compat.sh).

MBEDTLS_DEPRECATED_REMOVED is turned off in full since we don't want
to turn off deprecated features. Also turn off
MBEDTLS_DEPRECATED_WARNING since we wouldn't want expected warnings:
we're aware that we're enabling deprecated modules.
Since MBEDTLS_DEPRECATED_WARNING is excluded from full, it doesn't
need to be excluded from baremetal explicitly.

Ensure that there is a build with -pedantic in the full config, not
just in "exotic" configurations.

Don't use string literals that are longer than 4095 bytes, which is
the minimum that C99 compilers are required to support. Compilers are
extremely likely to support longer literals, but `gcc -std=c99 -pedantic`
complains.

<stdio.h> only declares the non-ISO-C function fileno() if an
appropriate POSIX symbol is defined or if using a compiler such as GCC
in non-pedantic mode. Define the appropriate POSIX symbol.

It works in practice on almost every platform, given that we're only
using the wrong type in cases where the value is guaranteed to stay
within the value bits of a signed int. But even in this case it may or
may not be strictly conforming. Anyway `gcc -std=c99 -pedantic`
rejects it.

GCC and Clang accept
```
typedef struct foo foo_t;
typedef struct foo { ... } foo_t;
```
But this is not valid ISO C due to the redefinition of `foo_t`.

It started out as be experimental, but it is now robust enough not to
break the rest, so there's no reason to leave it out.
