Some UART Controllers (Synopsys DesignWare 8250) will trigger spurious interrupts when the Line Control Register (LCR) is set while the UART is busy. This patch provides the option (16550_WAIT_LCR) to wait for UART until it's not busy, before setting the LCR. (16550_WAIT_LCR is disabled by default)
This patch fixes the spurious UART interrupts for the upcoming port of NuttX to StarFive JH7110 SoC (with Synopsys DesignWare 8250 UART). [The patch is explained here](https://lupyuen.github.io/articles/plic#appendix-fix-the-spurious-uart-interrupts)
drivers/serial/uart_16550.c: If 16550_WAIT_LCR is enabled, wait until UART is not busy before setting LCR
include/nuttx/serial/uart_16550.h: Define the UART Status Register (USR) for checking if UART is busy
drivers/serial/Kconfig-16550: Added option 16550_WAIT_LCR to 16550 UART Config, disabled by default
No memory map count limit that will exhaust memory and cause
the system hang. Also that fix pass LTP posix case mmap/24-1.c

When other code use nuttx memory manager by call mm_xx api directly,
it better to let other code to control weather dump or panic when
malloc failed.

Before directly use sched_backtrace() with SCHED_BACKTRACE disable will
lead compile error, this commit avoid this problem by define
sched_backtrace to 0 when CONFIG_SCHED_BACKTRACE not enable.

1. add lib_fork api in libs/libc, we need a fork() api to implement the
fork relative method, such as pthread_atfork
2. rename the assembly fork entry function name to up_fork(), and rename
the up_fork() to arch specific name, such as
sim_fork()/arm_fork()/mips_fork() etc.

you can debug nuttx through any transport layer (serial port, network etc.),
currently supports the following functions:
1. Read and write registers
2. Read and write memory
3. Switch thread and read stack information
Future support plans:
1. Support breakpoint, watch point (requires architecture support).
