a02f450773 board/ctrl: add BOARDCTL_SWITCH_BOOT switch boot system support
BOARDIOC_SWITCH_BOOT is required to communicate the boot partition from
userspace (OTA subsystem) to board. It can be used to change the system
boot behavior. So it's useful for A/B boot or even single boot case.

For the board support A/B boot case:
1. Download the new image from the sever
2. Write the new image to the alternative partition
3. Call BOARDCTL_SWITCH_BOOT to the alternative system

For single boot partition case:
1. Download the new image from the sever
2. Call BOARDCTL_SWITCH_BOOT and reboot to a small system
3. Write the new image to the main partition in the small system
4. Call BOARDCTL_SWITCH_BOOT again to the main system

This reverts commit cc514d7791.

* It introduced a regression.

* It seems conceptually wrong to have per-process data in

ae216cf9e9 sched/task: Simplify the syscall handling of task_spawn
It's better to save one argument by returning pid directly.
This change also follow the convention of task_create.
BTW, it is reasonable to adjust the function prototype a
little bit from both implementation and consistency since
task_spawn is NuttX specific API.

ebdfd16f0f Move gettid() implementation to /libs/libc/unistd
Move sched/task/task/task_gettid.c to libs/libc/unistd/lib_gettid.c.  gettid() is a dumb wrapper around getpid().  It is wasteful of resources to support TWO systme calls, one for getpid() and one for gettid().  Instead, move gettid() in the C library where it calls the single sysgtem call, getpid().  Much cleaner.

a354b9a9d1 fs/vfs: Implement EPOLLONESHOT flag
https://linux.die.net/man/2/epoll_ctl:
EPOLLONESHOT (since Linux 2.6.2)
Sets the one-shot behavior for the associated file descriptor.
This means that after an event is pulled out with epoll_wait(2)
the associated file descriptor is internally disabled and
no other events will be reported by the epoll interface.
The user must call epoll_ctl() with EPOLL_CTL_MOD to
rearm the file descriptor with a new event mask.

b89737395b vfs/epoll: add epoll_create1(2) implement
Linux Programmer's Manual

NAME
       epoll_create, epoll_create1 - open an epoll file descriptor

...
SYNOPSIS
       #include <sys/epoll.h>

       int epoll_create1(int flags);
...

   epoll_create1()
       If flags is 0, then, other than the fact that the obsolete
       size argument is dropped, epoll_create1() is the same as
       epoll_create(). The following value can be included in flags
       to obtain different behavior:

       EPOLL_CLOEXEC
              Set the close-on-exec (FD_CLOEXEC) flag on the new file
              descriptor. See the description of the O_CLOEXEC flag in
              open(2) for reasons why this may be useful.

DESCRIPTION

  EPOLL_CTL_DEL

       The event argument describes the object linked to the file descriptor
       fd.  The struct epoll_event is defined as:

           typedef union epoll_data {
               void        *ptr;
               int          fd;
               uint32_t     u32;
               uint64_t     u64;
           } epoll_data_t;

           struct epoll_event {
               uint32_t     events;      /* Epoll events */
               epoll_data_t data;        /* User data variable */
           };

1c002e1049 fs/vfs/fs_fstat: Correct fstat() for proxied block and MTD drivers.
Block and MTD drivers may be opened and managed as though they were character drivers.  But this is really sleight of hand; there is a hidden character driver proxy that mediates the interface to the block and MTD drivers in this case.

fstat(), however, did not account for this.  It would report the characteristics of the proxy character driver, not of the underlying block or MTD driver.

This change corrects that.  fstat now checks if the character driver is such a proxy and, if so, reports the characteristics of the underlying block or MTD driver, not the proxy character driver.
