- Add resize to the allocator interface
- Rework the trampoline variables in the obj struct
to make better sense of what is happening
Closes #4944

|
- Load symbols before allocation.
- Parse reloc records and place any reloc recs in a cache to use
while the allocator is locked.
- Relocate symbols after section allocation.
- Split section loading into allocation/locating and loading.
- Update all arch back-ends with a new reloc interface to control
tramp handling.
- Add `-a` and `-t` to the object list shell command.
Closes #3741

- Add support for architecure sections that can be handled by the
architecture back end.
- Add trampoline/fixup support for PowerPC. This means the PowerPC
now supports large memory loading of applications.
- Add a bit allocator to manage small block based regions of memory.
- Add small data (sdata/sbss) support for the PowerPC. The support
makes the linker allocated small data region of memory a global
resource available to libdl loaded object files.

Updates #3685

- Add trampolines to support relocs that are out of range on
support architectures.
- Support not loading separate text/data sections in an object
file if the symbol provided in the section is a duplicate.
A base image may have pulled in part of an object and another
part needs to be dynamically loaded.
- Refactor the unresolved handling to scale to hundreds of
unresolved symbols when loading large number of files.
Updates #3685

- Trampolines or fixups for veneers provide long jump support
for instruciton sets that implement short relative address
branches. The linker provides trampolines when creating a
static image. This patch adds trampoline support to libdl
and the ARM architecture.
- The dl09 test requires enough memory so modules are outside
the relative branch instruction ranges for the architecture.

Prepare for header file move to common include directory.
Update #3254.

This has been tested on SPARC, i386, PowerPC and ARM.
Closes #2767.

This is a merge of the RTL project.
