* set permissions to kernel read/write, no user access
for initially mapped memory areas
* set permissions to kernel read/write, no execute,
no user access for UART
Kernel:
* physical memory mapper uses kernel read/write mapping
with no-execute bit enabled
* all other pages are mapped as read/write/execute for
kernel and user
* proper access permissions and memory types to be
implemented later
Enforce memory access permissions by setting DACR to
client mode for domain #0, no access for other domains.
see ARM Architecture Reference Manual, section B3.7 Memory access control
and in particular the following subsections:
B3.7.1 Access permissions
B3.7.2 Execute-never restrictions on instruction fetching
B3.7.3 Domains, Short-descriptor format only

AP flags are not filled in at this point

Some programs use C11 threads instead of POSIX threads, so this change
implements a light wrapper around POSIX threads that conforms to the
C11 spec.
This code was primarily taken from FreeBSD, with minor modifications:
- The header file was trimmed to only include functions in the C11
spec, and changed to match the format of other Haiku header files
- The thrd_yield function was implemented with its POSIX equivalent
sched_yield instead of the non-standard pthread_yield
- The thrd_create function was changed to return thrd_busy on an
EAGAIN error code instead of unconditionally returning thrd_error
The respective files can be found in the FreeBSD source tree at:
- lib/libstdthreads/threads.h
- lib/libstdthreads/thrd.c
TODO:
- untested (is a unit test in order?)

ARM ABI has different alignment requirements based on parameter size:
* parameters not larger than 4 bytes are aligned on 4 bytes
* parameters larger than 4 bytes are aligned on 8 bytes
see:
Procedure Call Standard for the Arm Architecture
sections 5.1, Fundamental Data Types
and 6.5, Parameter Passing
Therefore the following changes are introduced in gensyscalls tool:
* new optional define SYSCALL_LONG_PARAMETER_ALIGNMENT_TYPE is introduced
* it's defined only on ARM
* on other architectures it takes on the value of SYSCALL_PARAMETER_ALIGNMENT_TYPE as a default
* constants kLongParameterAlignmentType and kLongParameterAlignmentSize are introduced
* Syscall::AddParameter uses this value for aligning parameters larger than 4 bytes
