1. support doublebuffer swtich for overlay layer
2. Add display area ioctl to scale the active area of the overlay layer
to a specific region on the LCD through hardware.

Function gpio_lower_half_byname() was added to support registration of
GPIO pin by name as supported for IOexpander. Some of the code is wrapped
in new static function gpio_lower_half_internal() to avoid code
duplication.

This adds support for 16 bit io expander pcf8575. The driver is basically
the same as for pcf8574 however it is for 16 bits instead of 8 bits. Since
pcf8575 and pcf8574 can be both used on the same i2c bus the driver for
pcf8575 is implemented in a different file to reduce the code size
and complexity and to have less if statements in the driver.

reproduce:
static void *pthread(void *arg)
{
system(arg);
}
void test (int argc, char *argv[])
{
pthread_create(&pthread0, &attr, pthread, argv[1]);
pthread_create(&pthread1, &attr, pthread, argv[2]);
}
only one pthread system() returnd, othres hanged
rootcause:
As we known, system() will create a new task called:
system -c XX
The example:
parent group child groups
pthread0 -> waitpid() -> system -c ps -> exit() -> nxtask_signalparent()
pthread1 -> waitpid() -> system -c ls -> exit() -> nxtask_signalparent()
Each child group exit with function nxtask_signalparent(),
As we expect:
system -c ps will signal pthread0
system -c ls will signal pthread1
But actually:
system -c ps will signal pthread0/1
system -c ls will signal pthread0/1
As the spec, we know, this behavior is normal:
https://man7.org/linux/man-pages/man2/sigwaitinfo.2.html
So for this situation, when the signo is SIGCHLD, we broadcast.

Standard POSIX specification in URL “https://pubs.opengroup.org/onlinepubs/9699919799/functions/mq_timedsend.html” requires that "EBADF" be returned when message queue not opened for writing.So i update the related descriptions in this file, no function changed.

In POSIX standard spec https://pubs.opengroup.org/onlinepubs/7908799/xsh/mqueue.h.html, the field type in mq_attr should be long not size_t. And no logical judgment when mq_maxmsg <= 0 or mq_msgsize <= 0. In this change, i update the field type in mq_attr, and add the missing logical judgment.

In POSIX testcase "open_posix_testsuite/conformance/interfaces/mq_receive/11-2.c", it will return "EPERM" when message queue is not opened for reading, but the standard POSIX specification in URL “https://pubs.opengroup.org/onlinepubs/9699919799/functions/mq_receive.html” requires that "EBADF" be returned.So in this change, i update it.
