This change reflects that the geometry isn't related to the largest
allocatable unit on the platform.
Calls to read and write block devices are also affected and have
been updated.
let's call either nx_dup/nx_dup2 or file_dup/file_dup2
instead just like other fs api: xxx->nx_xxx->file_xxx

the argument passed to file_dup2 doesn't always come from task file list
so it doesn't make sense to hold the file list lock and then it is better
to do the protection in the new function files_dupfd2

NULL inode passed to files_allocate doesn't mark file struct in the
allocated state, so other threads which invovle in file allocation
(e.g. open or dup) may allocate the same file struct again.

Withtout this change, I was not able to read images built
with the following tools:

Introduce a new Kconfig option, SPIFFS_COMPAT_OLD_NUTTX,
for those who prefer to keep the on-disk (bug-to-bug?) compatibility
with the older NuttX.
1. remove descript management in mqueue, save code size
2. use i_ops instead of i_mqueue to remove the dup logic

In current implementation, the asynchronous call "epoll_ctl()" unable
to wakeup the thread if pending on "epoll_wait()", the newly
added/delete FD cannot be used in the current waiting list,
this patch uses a reserved file object to wake up pending poll internal,
re-traverse the waiting list when a new event comes.

wget is missing from some system (like macOS and Windows native),
it's better to use curl to simplify build environment.

since the stdin, stdout and stderr may initialize later
in userspace if CONFIG_DEV_CONSOLE isn't enabled.
Note: it isn't bigger issue here to skip the check because
vfs will check the validation again in read and write syscall
