Remove 300-bn_mul.h-Use-optimized-MULADDC-code-only-on-ARM-6.patch,

(cherry picked from commit 49d96ffc5c)
This introduces a new Kconfig option to switch on/off mbedtls' support
for debug functions.
The idea behind is to inspect TLS traffic with Wireshark for debug
purposes. At the moment, there is no native or 'nice' support for
this, but at
68aea15833
an example implementation can be found which uses the debug functions
of the library. However, this requires to have this debug stuff enabled
in the library, but at the moment it is staticly patched out.
So this patch removes the static part from the configuration patch
and introduces a dynamic config file editing during build.
When enabled, this heavily increases the library size, so I added
a warning in the Kconfig help section.

In the case of upstream libraries, set the ABI_VERSION variable to the
soname value of the first version version after the last backwards
incompatible change.
For custom OpenWrt libraries, set the ABI_VERSION to the date of the
last Git commit doing backwards incompatible changes to the source,
such as changing function singatures or dropping exported symbols.
The soname values have been determined by either checking
https://abi-laboratory.pro/index.php?view=tracker or - in the case
of OpenWrt libraries - by carefully reviewing the changes made to
header files thorough the corresponding Git history.
In the future, the ABI_VERSION values must be bumped whenever the
library is updated to an incpompatible version but not with every
package update, in order to reduce the dependency churn in the
binary package repository.

With deterministic ECDSA the value k needed for the ECDSA signature is
not randomly generated any more, but generated from a hash over the
private key and the message to sign. If the value k used in a ECDSA
signature or the relationship between the two values k used in two
different ECDSA signatures over the same content is know to an attacker
he can derive the private key pretty easily. Using deterministic ECDSA
as defined in the RFC6979 removes this problem by deriving the value k
deterministically from the private key and the content which gets
signed.
The resulting signature is still compatible to signatures generated not
deterministic.
This increases the size of the ipk on mips 24Kc by about 2 KByte.
old:
166.240 libmbedtls_2.11.0-1_mips_24kc.ipk
new:
167.811 libmbedtls_2.11.0-1_mips_24kc.ipk
This does not change the ECDSA performance in a measurable way.

Disable MBEDTLS_SHA256_SMALLER implementation, not enabled by default in
upstream and reduces performance by quite a bit.
Source: include/mbedtls/config.h
Enable an implementation of SHA-256 that has lower ROM footprint but also
lower performance.
The default implementation is meant to be a reasonnable compromise between
performance and size. This version optimizes more aggressively for size at
the expense of performance. Eg on Cortex-M4 it reduces the size of
mbedtls_sha256_process() from ~2KB to ~0.5KB for a performance hit of
about 30%.
The size of mbedtls increased a little bit:

Fixed an authentication bypass issue in SSL/TLS. When the TLS
authentication mode was set to 'optional',
mbedtls_ssl_get_verify_result() would incorrectly return 0 when the
peer's X.509 certificate chain had more than
MBEDTLS_X509_MAX_INTERMEDIATE_CA intermediates (default: 8), even when
it was not trusted. This could be triggered remotely on both the client
and server side. (Note, with the authentication mode set by
mbedtls_ssl_conf_authmode()to be 'required' (the default), the handshake
was correctly aborted).
