trivial: Simplify the spots that use TARGET_BIG_ENDIAN as a numeric value

TARGET_BIG_ENDIAN is *always* defined, either as 0 for little endian
targets or as 1 for big endian targets. So we can use this as a value
directly in places that need such a 0 or 1 for some reason, instead
of taking a detour through an additional local variable or something
similar.

Several callers of load_elf() pass pointers for lowaddr and highaddr

hw/core/loader: Let load_elf() populate a field with CPU-specific flags

While loading the executable, some platforms (like AVR) need to
detect CPU type that executable is built for - and, with this patch,
this is enabled by reading the field 'e_flags' of the ELF header of
the executable in question. The change expands functionality of
the following functions:

- load_elf()
- load_elf_as()
- load_elf_ram()
- load_elf_ram_sym()

The argument added to these functions is called 'pflags' and is of
type 'uint32_t*' (that matches 'pointer to 'elf_word'', 'elf_word'
being the type of the field 'e_flags', in both 32-bit and 64-bit
variants of ELF header). Callers are allowed to pass NULL as that
argument, and in such case no lookup to the field 'e_flags' will
happen, and no information will be returned, of course.

Include sysemu/reset.h a lot less

In my "build everything" tree, changing sysemu/reset.h triggers a
recompile of some 2600 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

The main culprit is hw/hw.h, which supposedly includes it for
convenience.

Include sysemu/reset.h only where it's needed. Touching it now
recompiles less than 200 objects.

elf: Add optional function ptr to load_elf() to parse ELF notes

This patch adds an optional function pointer, 'elf_note_fn', to
load_elf() which causes load_elf() to additionally parse any
ELF program headers of type PT_NOTE and check to see if the ELF
Note is of the type specified by the 'translate_opaque' arg.
If a matching ELF Note is found then the specfied function pointer
is called to process the ELF note.

Passing a NULL function pointer results in ELF Notes being skipped.

The first consumer of this functionality is the PVHboot support
which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while
loading the uncompressed kernel binary in order to discover the
boot entry address for the x86/HVM direct boot ABI.
