Build

• Using MSYS2 clang64 environment with mingw-w64-clang-x86_64-toolchain packages group, LLVM version 14 and up, run mingw32-make command. (magiskboot.exe will appear in the out folder).
• if built a non-static variant, all DLLs in out/obj/lib/shared must be present in your PATH for successful execution.

What's changed:

• cpio action extract with no paramaters to ramdisk folder in current directory.
  • it creates cpio file to allow mode/uid/gid changes in Windows (with sync or pack)
• new cpio action sync that synchronize incpio entries with ramdisk directory (as new cpio). Any changes will be captured and dumped to incpio.
• new cpio action pack as follows: cpio pack [-c <config>] <infolder> <outcpio>
  • if <config> is undefined cpio is looked-up instead.

For Windows

• There's some UBs/SFs that needs to be addressed (test and report).
• Tested and working operations are limited.
