This vim settings were part of the initial commit. But no reason
to keep them.

Use atomic_flag type and the GCC __sync built-in functions for atomic
memory access. Initialize using ATOMIC_FLAG_INIT as a compound literal
or a cast if scalar type depending on which atomic.h is used.
The Linux client clears shared memory in ipi_shmem_echo().
Do not clear it again from the RPU in ipi_shmem_echod() to avoid a race.

In v2019.1, the xilmem and xilstandalone libraries were removed from
the standalone Xilinx BSP for the R5. This change adds a CMake
variable, XILINX_PRE_V2019, to conditionally add these libraries
to the link command for use with older BSPs.

Inclusion of error.h in example shmem_throughput_demo.c leads to
build failure when using musl instead of glibc as C library.
The file does not use any error.h specific functions, only the
error codes which are defined in errno.h. So the include can be
changed to errno.h.

As libmetal library has changed not to enable interrupts during
handler registration, application will need to enable the IRQs
after registration and disable IRQs before unregistration.

Use libmetal Xilinx IRQ controller for interrupt handling.
Libmetal abstracts interrupt controller imlementation.
Different platform can have their own interrupt controller
impelementation. There is Xilinx IRQ controller libmetal
implementation to work with Xilinx provided standalone
IRQ controller driver. The example makes use of this
libmetal Xilinx IRQ controller implementation.

With updated IRQ APIs, enable the IRQs after registration as
the IRQ registration will not enable the IRQs.

As IRQ registration is updated to only allow single handler
per IRQ, examples are updated to use the new APIs.
