This reduces open coding and allows to easily add a knob to
enable it treewide, where chosen packages can still opt-out via
"no-gc-sections".
Note: libnl, mbedtls and opkg only used the CFLAGS part without the
LDFLAGS counterpart. That doesn't help at all if the goal is to produce
smaller binaries. I consider that an accident, and this fixes it.
Note: there are also packages using only the LDFLAGS part. I didn't
touch those, as gc might have been disabled via CFLAGS intentionally.

Changelog: https://github.com/Mbed-TLS/mbedtls/releases/tag/v2.28.2
This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for security issues.
Fixes the following CVEs:
* CVE-2022-46393: Fix potential heap buffer overread and overwrite in
DTLS if MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and
MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX.
* CVE-2022-46392: An adversary with access to precise enough information
about memory accesses (typically, an untrusted operating system
attacking a secure enclave) could recover an RSA private key after
observing the victim performing a single private-key operation if the
window size used for the exponentiation was 3 or smaller.

enable additional crypto algorithms for hostap
hostap uses local implementations if not provided by crypto library,
so might as well enable in the crypto library for shared use by others.

<https://github.com/ARMmbed/mbedtls/releases/tag/v2.28.0>
"Mbed TLS 2.28 is a long-time support branch.
It will be supported with bug-fixes and security
fixes until end of 2024."
<https://github.com/ARMmbed/mbedtls/blob/development/BRANCHES.md>
"Currently, the only supported LTS branch is: mbedtls-2.28.
For a short time we also have the previous LTS, which has
recently ended its support period, mbedtls-2.16.
This branch will move into the archive namespace around the
time of the next release."
this will also add support for uacme ualpn support.

Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
This fixes the following security problems:
* Zeroize several intermediate variables used to calculate the expected
value when verifying a MAC or AEAD tag. This hardens the library in
case the value leaks through a memory disclosure vulnerability. For
example, a memory disclosure vulnerability could have allowed a
man-in-the-middle to inject fake ciphertext into a DTLS connection.
* Fix a double-free that happened after mbedtls_ssl_set_session() or
mbedtls_ssl_get_session() failed with MBEDTLS_ERR_SSL_ALLOC_FAILED
(out of memory). After that, calling mbedtls_ssl_session_free()
and mbedtls_ssl_free() would cause an internal session buffer to
be free()'d twice. CVE-2021-44732

session tickets are a feature of TLSv1.2 and require less memory
and overhead on the server than does managing a session cache
Building mbedtls with support for session tickets will allow the
feature to be used with lighttpd-1.4.56 and later.

This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for security issues.
Security fixes:
* Fix a buffer overflow in mbedtls_mpi_sub_abs()
* Fix an errorneous estimation for an internal buffer in
mbedtls_pk_write_key_pem()
* Fix a stack buffer overflow with mbedtls_net_poll() and
mbedtls_net_recv_timeout()
* Guard against strong local side channel attack against base64 tables
by making access aceess to them use constant flow code

A compact patch that provides AES and GCM implementations that utilize the
ARMv8 Crypto Extensions. The config flag is MBEDTLS_ARMV8CE_AES_C, which
is disabled by default as we don't do runtime checking for the feature.
The new implementation lives in armv8ce_aes.c.
Provides similar functionality to https://github.com/ARMmbed/mbedtls/pull/432
Thanks to Barry O'Rourke and others for that contribtion.
Tested on a Cortex A53 device and QEMU. On a midrange phone the real AES-GCM
throughput increases about 4x, while raw AES speed is up to 10x faster.
[updated Makefile to enable this function, adjusted commit message]
