License-Update: Copyright year updated to 2024.

Changelog:
==========
- Improved detection of bad remote storage URLs gracefully. This also fixes
  crashes seen in ccache's own test suite. +

  is detected during ccache invocation. Previously this was only done for the
  direct mode. +
- Fixed a MSVC crash when using '/Zi' with many concurrent compilations. +
