The goal is to kill the massive target ifdef ladder in elfload.c.
The functions get moved to linux-user/target/elfload.c.
The macros get moved to linux-user/target/target_elf.h.
These are mostly use to parameterize include/elf.h or elfload.c.
The init_thread functions, storing into target_pt_regs, have been
merged with target_cpu_copy_regs, copying out of target_pt_regs
into CPUArchState. Merging these found a few bits of silliness
where pt_regs fields were initialized but not used. To encourage
this never to return, remove most target_pt_regs and hide the rest
within the relevant signal.c.
Changes for v2:
- Cleanup semihosting user-only SYS_HEAPINFO.
- No more weak functions. Replaced with HAVE_* macros and
strong fallback functions. If the HAVE_* macro is missing
and the target provides its own function, we'll get a link
error for duplicate symbols.
- No more target_coredump.c.inc. This required killing
target_elf_gregset_t so that the function signatures could
match for all targets.
- Misc other changes from review.
