Features and Changes:
Note >> for compatibility/configuration changes
- >> Disable DROPBEAR_DSS by default
It is only 1024 bit and uses sha1, most distros disable it by default already.
- Added DROPBEAR_RSA_SHA1 option to allow disabling sha1 rsa signatures.
>> RSA with sha1 will be disabled in a future release (rsa keys will continue
to work OK, with sha256 signatures used instead).
- Add option for requiring both password and pubkey (-t)
Patch from Jackkal
- Add 'no-touch-required' and 'verify-required' options for sk keys
Patch from Egor Duda
- >> DROPBEAR_SK_KEYS config option now replaces separate DROPBEAR_SK_ECDSA
and DROPBEAR_SK_ED25519 options.
- Add 'permitopen' option for authorized_keys to restrict forwarded ports
Patch from Tuomas Haikarainen
- >> Added LTM_CFLAGS configure argument to set flags for building
bundled libtommath. This also restores the previous arguments used
in 2020.81 (-O3 -funroll-loops). That gives a big speedup for RSA
key generation, which regressed in 2022.82.
There is a tradeoff with code size, so -Os can be used if required.

- Add '-z' flag to disable setting QoS traffic class. This may be necessary
to work with broken networks or network drivers, exposed after changes to use
AF21 in 2022.82

Reported by yuhongwei380, patch from Petr Štetiar
- Allow overriding user shells with COMPAT_USER_SHELLS
Based on a patch from Matt Robinson
- Improve permission error message
Patch from k-kurematsu

Regression fixes from 2022.82:
- Fix X11 build
- Fix build warning
- Fix compilation when disabling pubkey authentication
Patch from MaxMougg
- Fix MAX_UNAUTH_CLIENTS regression

Other fixes:
- Fix long standing incorrect compression size check. Dropbear
(client or server) would erroneously exit with
"bad packet, oversized decompressed"
when receiving a compressed packet of exactly the maximum size.
- Fix missing setsid() removed in 2020.79

Reported and debugged by m5jt and David Bernard
- Try keyboard-interactive auth before password, in dbclient.
This was unintentionally changed back in 2013
