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.
