Not all headers can be used by 32 bit boot code.
Allows to override some headers, we don't want to mess up with
main headers as most of the code is only 64 bit so the easy stuff should
be done for 64 bit declarations.
Boot headers should be 64 bit compatibles to avoid having multiple
declarations.
Move some assembly code to C.

As a continuation of this series start sorting out the issue of headers
not compatible with 32 bit.
Instead of having to change headers which are almost only used for 64 bit
allows to override headers or move reusable definitions to new shared
headers.
This results in less changes.
Changes since v
This allows to include other headers and avoid duplicated declarations.

Enable previously added CONFIG_STACK_PROTECTOR feature for ARM
platform. Here we can call boot_stack_chk_guard_setup() in start_xen()
function, because it never returns, so stack protector code will not
be triggered because of changed canary.

Both GCC and Clang support -fstack-protector feature, which add stack
canaries to functions where stack corruption is possible. This patch
makes general preparations to enable this feature on different
supported architectures:
- "-fno-stack-protector" is removed from global config
- Added CONFIG
