* Switch from wolfssl to mbedtls as default
OpenWrt has transitioned its default cryptographic library from wolfssl to mbedtls. This shift brings several changes and implications:

Size Efficiency: mbedtls is considerably smaller, making it an optimal choice for systems where storage space is paramount.
LTS and ABI Stability: mbedtls consistently provides updates via its Long Term Support (LTS) branch, ensuring both security and a stable application binary interface (ABI). In contrast, wolfssl does not offer an LTS release, and its stable ABI is limited to a specific set of functions.
TLS 1.3 Support: Users should be aware that mbedtls 2.28 no longer supports TLS 1.3.
While mbedtls is now the default, users who have specific needs or preferences can still manually switch back to wolfssl or choose openssl.

* Rust Package Support
This release introduces the ability to include rust-written programs into the OpenWrt package infrastructure. Examples are: bottom, maturin, aardvark-dns and ripgrep.

* Core components update
Core components have the following versions in 23.05.0:

- Updated toolchain:
musl libc 1.2.4
glibc 2.37
gcc 12.3.0
binutils 2.40
Updated Linux kernel
5.15.134 for all targets
- Network:
hostapd master snapshot from September 2023
dnsmasq 2.89
dropbear 2022.82
cfg80211/mac80211 from kernel 6.1.24
- System userland:
busybox 1.36.1

* Upgrading to 23.05.0
Sysupgrade can be used to upgrade a device from 22.03 to 23.05, and configuration will be preserved in most cases.

- Sysupgrade from 21.02 to 23.05 is not officially supported.
- ipq40xx EA6350v3, EA8300, MR8300 and WHW01 require tweak to the U-Boot environment on update from 22.03 to 23.05. Refer to the Device wiki or the instruction on sysupgrade on how to do this change. Config needs to be reset on sysupgrade.

* Known issues
lantiq/xrx200 target is not build because the DSA driver for the integrated GSWIP switch shows some error messages.
bcm53xx: Netgear R8000 and Linksys EA9200 Ethernet is broken
