Update #4020.

Clearing the std file handles when the main loop exited crashes
telnetd as it reuses its session threads.

Add a new directory for Doxygen-specific documentation content. Add a
Doxygen only header file containing documentation of the application
configuration options. The header file is generated from specification
items.
Close #3994.

Since we need to test the strncpy function, using a character array with
a fixed array size in this case in place of character pointer can avoid
the string turncation warning.

The external UART over SPI device SC16IS752 uses the interrupt server
for interrupt processing. The interrupt server is also heavily used by
libbsd. The interrupt processing for the SC16IS752 is time critical and
doesn't work if network traffic is processed at the same priority.
With #4033 custom interrupt servers are available. Change
atsam_sc16is752_spi_create() to support user-defined interrupt servers.
Introduced atsam_sc16is752_spi_config to cut down the argument count of
this function.
Close #4039.

This mutex is used to maintain termios internal data structures.

This addresses compiler warnings like this:
warning: array subscript 0 is outside the bounds of an interior
zero-length array 'abc[0]' [-Wzero-length-bounds]

Currently if mount fails, a converter isn't destroyed. We have to take
care of two cases:
1. The user doesn't provide a converter.
In this case mounting a dosfs creates a default converter. This patch
makes sure that the converter is destroyed again if mount failes for
this case.
2. The user provides a converter.
In this case it's not sure that the dosfs specific routines are reached
because mount can fail before that. Therefore the user has to destroy
the converter himself again. This patch adds a documentation for that
and implements it in the media server.
Closes #4042.

Add rtems_interrupt_server_destroy().
Before this patch, the only way to create interrupt servers was
rtems_interrupt_server_initialize(). This function creates the default
interrupt server and in SMP configurations additional interrupt servers
for the additional processors. The interrupt server is heavily used by
libbsd. This includes the epoch based reclamation which performs time
consuming resource and memory deallocation work. This does not work well
with time critical services, for example an UART over SPI or I2C. One
approach to address this problem is to allow the application to create
custom interrupt servers with the right priority and task properties.
The interrupt server API accounted for this, however, it was not
implemented before this patch.

The cache of the fdt blob is flushed after copy. Therefore it should be
aligned.

The chip select lines of the iMX SPI module doesn't work well for a
generic API like the one RTEMS uses. The existing solution only worked
in some special cases and had odd bugs when trying transfers of
different sizes (like deselecting between each byte for lengths that are
not dividable by 4).
With this patch the same approach like on FreeBSD or Linux is used:
Treat the CS lines as GPIOs.

Having a duplicate header with the shared includes is a build system
inconsistency. You may use one header file to build the libraries and
another one is installed (overwriting the other).

Make sure that the esp is restored before the eflags register.
When the init task is initially restored, system interrupts are activated when the
eflags register is loaded.
If the esp register still points to an address in the interrupt stack
area (from early system initlization) the ISR might overwrite its own
stack.
Closes #4031

Only include the deferred free support if free() is actually used by the
application.
The free() implementation in RTEMS supports that allocated memory is
freed in interrupt context. Since the heap is protected by a mutex, the
frees issued in interrupt context cannot immediately be freed to the
heap, instead they are placed on a deferred free list. This list is
emptied by the core allocation function
rtems_heap_allocate_aligned_with_boundary(). This adds a dependency to
free() in rtems_heap_allocate_aligned_with_boundary(). In order to
better support applications which only allocate memory and never free
it, this dependency should be avoided. Provide a weak default
implementation of _Malloc_Process_deferred_frees() for
rtems_heap_allocate_aligned_with_boundary(). In the free() module
provide the strong implementation.
Close #4032.

These two tests check conditions which no longer exist in the thread
queue implementation. The are obsolete since the change to use
red-black trees for the priority queues.

This macro magic is in line with C11 and C++11, but limits the maximum

Rename internal function T_check_true() to T_check() and use the new
flag T_CHECK_FMT to indicate if a format string is present. This is a
preparation step to make the format string optional.
Make the check context the first parameter.
The API remains the same.
