* SWDEV-517078 - Maintain the trap handler ABI version in CLR
The trap handler ABI version is communicated to the debugger using
the r_version field in the r_debug structure. This structure is
an external dependency, which makes it complicated to keep the trap
handler source (in CRL) and the ABI version number (external dependency)
in sync.
This patch proposes to patch the trap handler ABI version number in
_amdgpu_r_debug before communicating it to the debugger.
We can't directly include sc's executable.hpp file in CRL as it relies
on conflicting definition of ELF related types, so instead we need to
rely on a-priori knowledge on the r_debug structure. Fortunately, this
structure is part of a stable ABI, so its layout is guaranteed to be
kept stable.
Update the 2nd level trap handler to follow updates from the
ROCr-runtime. The trap handlers are stripped from parts dedicated to
architectures unsupported by CLR.
Bump the r_debug.r_version to track the ABI changes in the trap handler.
Add trap handler code into runtime and compile/load during
device initialization. The current interface for trap handler in
PAL is obsolete and the new interface will be provided later.
