Follow the model of `MBEDTLS_SSL_CONF_ENDPOINT`. This saves a small
amount - most of the saving was already acheived via`
MBEDTLS_SSL_TRANSPORT_IS_TLS` but we can scrape out a little more by
totally eliminating `ssl->conf->transport` references.

Optimize the key switching mechanism to set the key only if
a different operation is performed with the context.

Store the raw encryption and decryption keys in transforms
to set them before each cipher operation. Add a config option
for this - MBEDTLS_SSL_TRANSFORM_OPTIMIZE_CIPHERS.

CRC is calculated when the key is set. This commit also adds new tests
for ecb encryption and decryption, simulating a fault injection after the key is set.

Add a new CRC module along with some tests for it.
The table and the CRC function body is generated using pycrc v0.9.2.

all.sh:
- component_build_deprecated - chosen the refactored version from 2.16.6,
but with extra flags from baremetal.
- rest of the _no_xxx tests - merged make options to have PTHREAD=1 and
other changes from 2.16.6 (like -O1 instead of -O0).

ssl_server2.c - Merged the 2.16.6 usage split with additional baremetal usages.
config.pl - fixed missing defines from the documentation, removed duplicates,
and reorganised so that the documentation and excluded list
are ordered in the same way.
test_suite_x509parse.data - only added the two new pathlen tests.
x509_crt.c - change the return code by removing
MBEDTLS_ERR_X509_INVALID_EXTENSIONS, since it's added by

Changelog - Assigned all entries to appropriate sections.
ssl-opt.sh - line 8263 - merged options.
- removed lines 1165 - 1176 - there was a duplicate test, probably
an artifact of previous merges.
check-files.py - sticked to old formatting.

You can't reuse a CTR_DRBG context without free()ing it and
re-init()ing. This generally happened to work, but was never
guaranteed. It could have failed with alternative implementations of
the AES module because mbedtls_ctr_drbg_seed() calls
mbedtls_aes_init() on a context which is already initialized if
mbedtls_ctr_drbg_seed() hasn't been called before, plausibly causing a
memory leak. Calling free() and seed() with no intervening init fails
when MBEDTLS_THREADING_C is enabled and all-bits-zero is not a valid
mutex representation. So add the missing free() and init().
Add a very basic test of calloc to the selftest program. The selftest
program acts in its capacity as a platform compatibility checker rather
than in its capacity as a test of the library.
The main objective is to report whether calloc returns NULL for a size
of 0. Also observe whether a free/alloc sequence returns the address
that was just freed and whether a size overflow is properly detected.
-Add config option for AES encyption only to config.h. Feature is
disabled by default.
-Enable AES encrypt only feature in baremetal.h configuration
-Remove AES encypt only feature from full config
- Do not include MBEDTLS_AES_ONLY_128_BIT_KEY_LENGTH to full config
as it requires also MBEDTLS_CTR_DRBG_USE_128_BIT_KEY
- Update check_config to check availability of flags:
MBEDTLS_AES_ONLY_128_BIT_KEY_LENGTH
MBEDTLS_CTR_DRBG_USE_128_BIT_KEY
Ultimately, mbedtls_hardware_poll() is going to be provided by the
OS/environment when running on target. But for on-host programs and tests, we
need to define (a fake version) in each program that we want to be able to
link.
A previous commit took care of ssl_client2 and ssl_server2. But if we want to
be able to compile all programs, we need to modify each of them. This doesn't
seem useful, so instead let's just build the programs we need for testing -
this means only udp_proxy needs fixing in addition to what's already done.
This issue went unnoticed in the PR that introduced the new all.sh component,
because at that time the platform_memxxx() functions were not actually used in
the library (nor in programs), so the linker could live with
mbedtls_hardware_poll() not being defined, as it wasn't called anywhere. This
changed when we started using the new platform_memxxx() functions in the
library.
This commit modifies the example programs ssl_client2 and ssl_server2
to allocate various structures on the heap instead of the stack. This
allows more fine-grained memory usage tracking via valgrind massif.
There is a static dependency in the test system for
this file. To prevent the issue from happening, move
the definition to the end of file so that the last
return in the main remains in the same line.
Use MBEDTLS_ENTROPY_HARDWARE_ALT instead of a new global RNG
flag. When this flag is enabled, the platform provides the RNG.
When running unit tests, rnd_std_rand should be used by overriding
the mbedtls_hardware_poll.
-Add comments to Makefiles about test env auto-detection
-Fix indentation
-Remove parent folder from include dirs
-Do not use environment variable for defining config file because
env variable usage is not fully implemented
