Backport five upstream libssh security fixes to the 0.10.6 recipe on
 scarthgap:

 - CVE-2026-59843
 - CVE-2026-59844
 - CVE-2026-59846
 - CVE-2026-59848
 - CVE-2026-59850

Carry these as focused backports instead of upgrading libssh because
newer releases include API and functional changes outside the security
scope.

CVE-2026-15370 and CVE-2026-59849 affect libssh >= 0.11.0.
CVE-2026-59842 and CVE-2026-59851 affect only libssh 0.12.0 and rely on
code or features absent from 0.10.6. NVD correction requests have been
submitted for these inaccurate affected-version entries; therefore, no
CVE_STATUS entries are added.

The individual commits retain the upstream fix provenance and advisory
references for each CVE.

Testing:
- Applied all five patches to libssh 0.10.6 in series order without
  conflicts or fuzz.
- Package build completed successfully.
