- 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.

This is an example test using the RTEMS Test Framework. It tests also
the framework itself.
Add T_FILE_NAME command line define to get rid of the full file path.
This is important to reduce the read-only data of test files and make
them build system independent.

- The archive command lists archives, symbols and any duplicate
symbols.
- Change the RTL shell commands to the rtems_printer to allow
the output to be captured.

- 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.

- 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.

- 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.

Add low level event recording infrastructure for system and user
defined events. The infrastructure is able to record high frequency
events such as
* SMP lock acquire/release,
* interrupt entry/exit,
* thread switches,
* UMA zone allocate/free, and
* Ethernet packet input/output, etc.
It allows post-mortem analysis in fatal error handlers, e.g. the last
events are in the record buffer, the newest event overwrites the oldest
event. It is possible to detect record buffer overflows for consumers
that expect a continuous stream of events, e.g. to display the system
state in real-time.
The implementation supports high-end SMP machines (more than 1GHz
processor frequency, more than four processors).
Add a new API instead. The implementation uses per-processor data
structures and no atomic read-modify-write operations. It is uses
per-processor ring buffers to record the events.
The CPU counter is used to get the time of events. It is combined with
periodic uptime events to synchronize it with CLOCK_REALTIME.
The existing capture engine tries to solve this problem also, but its
performance is not good enough for high-end production systems. The
main issues are the variable-size buffers and the use of SMP locks for
synchronization. To fix this, the API would change significantly.
Update #3665.

Tracking references lets us manage when an object file can be
unloaded. If an object file has references to it, it cannot be
unloaded.
Modules that depend on each other cannot be unloaded.

An RTEMS application default configuration is contained in
cpukit/libmisc/dummy/default-configuration.c. This default
configuration was contained in librtemscpu.a. This had at least two
problems:
1. Application configuration errors may have pulled in the default
configuration which in turn lead to multiply define symbols error.
This was quite confusing. You had to consult the linker map file to
figure out what cased the pull in of the default configuration. You
needed to know what a linker map file is and how you generate it with
your build system. This was not very user friendly.
2. It prevented the use of default configuration items for each subsystem
in librtemscpu.a. This may be used to reduce the size of the
configuration itself.
Move the default configuration to the separate library
librtemsdefaultconfig.a.

Disabling a warning does not prevent the compiler from reasoning what it
is supposed to do with a somewhat undefined function call.

The Telnet service started via rtems_telnetd_start() had a keep stdio
feature. This just created a task and executed the command function in
a loop. For this kind of service we do not library support. This can
be done by an application task on its own. Remove this feature and
provide only the real Telnet server functionality.
Use syslog() for error and status messages.
Add test program for the Telnet server.

Using CONFIGURE_MINIMUM_TASK_STACK_SIZE increases also the interrupt
stack size. This is an issue on some BSPs. Use
CONFIGURE_INIT_TASK_TABLE_SIZE instead.
