This contains a fix for:
CVE-2024-28960: An issue was discovered in Mbed TLS 2.18.0 through 2.28.x
before 2.28.8 and 3.x before 3.6.0, and Mbed Crypto. The PSA Crypto
API mishandles shared memory.

Fixes libssh, which requires it. Bump ABI_VERSION, since enabling this

This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for following security issues:
* Timing side channel in private key RSA operations (CVE-2024-23170)
Mbed TLS is vulnerable to a timing side channel in private key RSA
operations. This side channel could be sufficient for an attacker to
recover the plaintext. A local attacker or a remote attacker who is
close to the victim on the network might have precise enough timing
measurements to exploit this. It requires the attacker to send a large
number of messages for decryption.
* Buffer overflow in mbedtls_x509_set_extension() (CVE-2024-23775)
When writing x509 extensions we failed to validate inputs passed in to
mbedtls_x509_set_extension(), which could result in an integer overflow,
causing a zero-length buffer to be allocated to hold the extension. The
extension would then be copied into the buffer, causing a heap buffer
overflow.
Fixes: CVE-2024-23170, CVE-2024-23775

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.

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.

<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.

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.
