39957503c5 Remove secp256k1 from the default X.509 and TLS profiles 
For TLS, secp256k1 is deprecated by RFC 8422 §5.1.1. For X.509,
secp256k1 is not deprecated, but it isn't used in practice, especially
in the context of TLS where there isn't much point in having an X.509
certificate which most peers do not support. So remove it from the
default profile. We can add it back later if there is demand.

ec78bc47b5 Meld DEFAULT_ALLOW_SHA1_IN_CERTIFICATES removal migration guide 
Meld the migration guide for the removal of
MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_CERTIFICATES into the migration guide for
the strengthening of TLS and X.509 defaults, which is more general. The
information in the SHA-1 section was largely already present in the
strengthening section. It is now less straightforward to figure out how to
enable SHA-1 in certificates, but that's a good thing, since no one should
still be doing this in 2021.

b1940a76ad In TLS, order curves by resource usage, not size 
TLS used to prefer larger curves, under the idea that a larger curve has a
higher security strength and is therefore harder to attack. However, brute
force attacks are not a practical concern, so this was not particularly
meaningful. If a curve is considered secure enough to be allowed, then we
might as well use it.

So order curves by resource usage. The exact definition of what this means
is purposefully left open. It may include criteria such as performance and
memory usage. Risk of side channels could be a factor as well, although it
didn't affect the current choice.

The current list happens to exactly correspond to the numbers reported by
one run of the benchmark program for "full handshake/s" on my machine.

6a2fb61896 Rename library/ecp_alt.h to ecp_internal_alt.h 
library/ecp_alt.h (declaring individual functions of the ECP module that can
be substituted, included when building the library with
MBEDTLS_ECP_INTERNAL_ALT enabled) clashes with ecp_alt.h (not provided,
declaring types of the ECP module when the whole implementation is
substituted, included when building the library with MBEDTLS_ECP_ALT enabled).
Depending on the search path during build, this can make MBEDTLS_ECP_ALT
unusable.

Rename library/ecp_alt.h to follow the naming convention of other alt headers:
MBEDTLS_XXX_ALT corresponds to xxx_alt.h.

0e3b7ced4c Don't require a call to add_entropy when 0 bytes are needed 
If an RNG peripheral includes an entropy source, it would presumably
declare "initial_entropy_size" and "reseed_entropy_size" to be 0. In
this case, don't require the core to call "add_entropy".

5263e1ecdd Transparent drivers can have get_entropy as well 
The `get_entropy` entry point can be provided by multiple transparent
drivers, and the core will call all of them. But apart from that,
`get_entropy` doesn't involve an opaque key or a location, so it can
be in a transparent driver.

e80978a260 Specification for random generation and entropy drivers 
Transparent drivers may provide a DRBG interface through "add_entropy"
and "get_random" entry points. This interface may also be used with a
non-deterministic generator, for chips that include a TRNG.

Opaque driver may provide a "get_entropy" entry point.

1fc4c8d11b Let get_builtin_key be called to retrieve the key's attributes 
Allow the core to call the "get_builtin_key" entry point to retrieve
the attributes of a built-in key. This is useful to implement
psa_get_key_attributes(), and also when the key data buffer's size
depends on the key type and size.

51977355dc Remove the time stamp 
Having a time stamp identifying each revision of the document is
useful, but it's also a pain because it creates a conflict whenever
there are multiple pending changes at the same time. The gain isn't
worth the pain, so I'm removing the time stamp.

db6b03b4f2 Remove old-style accelerator and entropy driver interfaces 
The driver interfaces described in crypto_accel_driver.h and
crypto_entropy_driver.h are no longer being worked on. We do not
intend to finish the design of these interfaces or to implement them
in Mbed TLS. They have been superseded by the unified driver
interface (docs/proposed/psa-driver-interface.md), which is being
actively worked on both to finalize the specification and to implement
it in Mbed TLS.

The partially implemented dynamic secure element interface is staying
for now.

99e52f6313 Clarifications around key import 
Rework the section describing key import, in particular to clarify key
size determination and checking. There is no intended semantic change.

Note an open question around support for implementation-specific
import formats.
