697c57355b Disable old version before copying files 
Apparently some people still have the obsolete v1.5.1 installed
and manage to break things by copying v2.x config in place.

da16365508 Report if BCDEdit is not working 
One possible cause for BCDEdit failure is Windows error 0x800703EE.
"The volume for a file has been externally altered so that the opened file is no longer valid."
Suggested solutions include disabling antivirus or backup software.

665a4732ca Detect device paths which contain extra data 
Apparently some firmware may add extra data to the device path,
so exit the loop on the first end-of-path record.
Fixes GH issue #181.

a44b929012 Fix a shim error caused by bad load options data 
Shim expects a filename or nothing in the load options.

To avoid an error message during boot, do several things:

When creating the NVRAM entry, use empty load options. The current
string ("HackBGRT\0") was just a decoration, and it's luckily ignored
by shim because the length is odd.

When creating the entry with BCDEdit, manually fix the load options.
The load options in BCDEdit entries start with "WINDOWS\0" followed
by UINT32 version, as seen in ReactOS struct BL_WINDOWS_LOAD_OPTIONS.
The version is 1, but BCDEdit seems to be happy with a higher number.
By setting this version to 'X' (0x58), the string becomes a valid
UCS-2 file name. Update the installer so that the HackBGRT loader is
installed with this weird file name.

The reason why the load options cannot be deleted completely is that
BCDEdit will recreate the entry on next boot if it doesn't find the
entry it just tried to create.

8dfa456a7b Fix ARM (32-bit) build 
Use -O, because -O2 causes Undefined OpCode in QEMU / UEFI Shell.

Remove -mno-red-zone which triggers -Wunused-command-line-argument.

Set architecture in PE file manually:
EFI uses IMAGE_FILE_MACHINE_ARMTHUMB_MIXED = 0x01C2,
while the default is IMAGE_FILE_MACHINE_ARMNT = 0x01C4.
