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

               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.

There are two motivations for this change:  First, it reduces the number of system calls.  Secondly, it adds a common hook that is going to used for a future implementation of TLS.
