NuttX builtin up_udelay function uses BOARD_LOOPSPERMSEC configuration
value to determine how many loops need to be done to cause requested
delay. This does not match well with AVR DA/DB microcontrollers
because the CPU clock frequency is configurable.
A board configuration could therefore provide BOARD_LOOPSPERMSEC
valid for one frequency but for other frequencies, the user would
be required to calibrate the value and would still get incorrect
result when changing the clock speed during runtime.
This patch therefore implements dynamic architecture-specific
up_udelay function which determines current clock settings
and infers required loop count from that.
New function was tested by simple application that used up_udelay
to put delays between printf calls.

This patch adds support for reading CPU clock frequency when the MCU

While attempting to create architecture-specific implementation
of up_udelay, it was discovered that the overriding function is not
included in the final binary, the weak implementation was used instead.
Further investigation and experimentation showed that the linker
only overrides the weak implementation with the custom one if
the custom one is present in a .c source file that contains at least
one other function that is called from somewhere. Some additional
testing revealed that at least one other already present up_udelay
override (rv32m1-vega:nsh) is affected by this.
In a short mailing list discussion it was determined that this
is a likely result of using static libraries during the build process
and it was suggested to introduce configuration option that will
exclude weak implementations of the function from the build altogether.
This patch does that.
This patch does not enable this configuration option for any existing
board/chip because doing so would change its behaviour and needs
to be tested by users of the hardware.
Also changed is the static assertion in sched/clock/clock_delay.c
to not prevent building the code when architecture declares that
it does not use BOARD_LOOPSPERMSEC to determine required loop count.
BOARD_LOOPSPERMSEC is made undefined in such case.
Patch was tested by building breadxavr:nsh (identical binary by SHA256),
rv32m1-vega:nsh (identical text section) and rv-virt:nsh (text section
differs because of different ordering of functions in the binary, ostest
passed though.)

This patch amends commit dfd3426aa5 which added support for running
with some signals disabled to AVR architecture. AVR DA/DB architecture
was not covered by the commit and failed to build
with CONFIG_ENABLE_ALL_SIGNALS unset (which includes building
with CONFIG_ENABLE_PARTIAL_SIGNALS, the default value.)
Change is replicated from the commit and tested by a custom stress
application which spawns some always-busy threads and uses preemptive
multitasking to switch between them. Additionally, ability to sleep
in the application was tested by a simple LED blinking application.

This patch amends commit f077c0321d which is a part of series that
changed (in commit 48db502daf) default value of BOARD_LATE_INITIALIZE
to yes. With this change, the boards are required to provide
board_late_initialize function.
Commit f077c0321d added this function to many AVR boards but
not to this one, making the build with default configuration
fail. This patch rectifies that and provides an empty function.
With this patch applied, the build no longer fails.

Adds tg_suid and tg_sgid fields to task_group_s to complete the
POSIX three-field identity model (real, effective, saved-set).
Updates group_inherit_identity() to propagate the new fields from
parent to child task group on task creation.
Fixes setuid(), setgid(), seteuid(), and setegid() to implement
correct POSIX privilege transition logic:
- Root (euid==0): may set any value; all three IDs updated by setuid/setgid
- Non-root: may only set effective ID to real or saved value; else EPERM

This fixes an issue where ostest robust mutex test gets stuck.
In CONFIG_PTHREAD_MUTEX_ROBUST mode, every NORMAL mutex is robust by
definition, so the robust flag must be set to allow the mutex to be tracked
in the holder's mutex list.
Otherwise, pthread_mutex_add() will not record the mutex and
pthread_mutex_inconsistent() will not be able to mark it as inconsistent or
wake waiters when the holder thread terminates.

up_disableusartint() saves USART interrupt state from hardware CTL0-CTL3
registers but omits the CTL selector bits (bits 24-27) in the encoded
ie value. When up_restoreusartint() later restores interrupts, it uses
ie >> 24 to determine which CTL register to write. Without selector bits
this evaluates to 0, so no CTL register is updated and all interrupt
enables (including RBNEIE) are permanently lost.
This causes RX interrupts to never fire after any call to up_putc()
(e.g. via syslog), making the serial console unable to receive input.
Fix by adding the corresponding CTL selector bit (USART_CFG_CTLx_INT
<< USART_CFG_SHIFT) whenever a CTL register has active interrupt bits.
