[jessk-msft]

Version [1.29.4.0]

• Updating to latest P4API 25.2
• Migrating to OpenSSL 3.0 LTS as recommended by P4API 25.2 with latest 3.0.18
• Addition to default ExcludedProcessNames of MpDlpService.exe which is common Windows
  Defender application
• Optimization to use C++ transparent comparators on std::map<string,*,compare> to enable
  heterogeneous lookup from either c_str or string
• Addition of default property values to SettingManager. It is now used to test
  against combinations of default and overridden settings values
• Fixing bug where p4vfs.exe common option '-v' would not actually enable verbose logging
  for the command
• Addition of experimental configuration setting MaxDiff2StatFileCount for specifying
  the maximum number of files for when fstat commands should be used instead of diff2
  for determining the have & head filetype of files to sync. Using fstat can be
  faster than diff2 in the rare case where a very few number files are updated under a
  very large file spec. For that reason, we'll keep this feature disabled by default indefinitly.
  A MaxDiff2StatFileCount of zero (default) will use legacy behavior to only use
  diff2. A MaxDiff2StatFileCount of less than zero will always use fstat. A
  MaxDiff2StatFileCount of greater than zero will use fstat if the number of modifications
  are less than the value.
• Addition of a new verbose mode "Preview Time" profile time to the sync command which
  indicates the time spend gathering virtual sync file modifications to be applied.
