f974099b42 vfs: Fix potential select() race if both sock and other-fd trigger 
This fixes a potential race condition in select() if both a socket-fd
and non-socket fd trigger simultaneously to unblock this select.
In case of both fds, we use lwip's local thread semaphore, so we only
have to try return it (if it was taken/triggered more than once) when
we exit select().

vfs: don't overwrite errno by a hard coded ENOENT 
Calling "open" in CHECK_AND_CALL sets a perfectly correct errno.
There is no need to overwrite that with a value of ENOENT, since doing
so hides lower level errors like EIO.

cf21312d8d VFS: select function's timeout is now POSIX compliant

It  makes it POSIX compliant.

420aef1ffe Updates for riscv support 
* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
  longer signed/unsigned int).

Changes come from internal branch commit a6723fc

53f89464a3 vfs: fix invalid dereference for zero-length base_path 
When base_path has len == 0, the code used to compare base_path[-1]
with '/'. Fix by correcting the length check.
Also mention the case of zero-length base_path in the API reference.

cadab2cbcf vfs: define all implementations as esp_vfs_, create aliases 
This change allows (in the future) to test VFS on host, without having
it conflict with the host C library. On host, all aliases would be
disabled.

22514c1dd9 cmake: For gcc8 use linker to find paths to libc, libm, libstdc++, etc 
Removes the need to know/guess the paths to these libraries. Once we are gcc 8 only, we
can remove -nostdlib and no additional arguments are needed for system libraries.

The catch is: any time IDF overrides a symbol in the toolchain sysroot, we need
an undefined linker marker to make sure this symbol is seen by linker.

552ba35da5 add missing ioctl declaration 
Previously ioctl was declared as a macro in lwip/sockets.h.
Disabling LWIP_POSIX_SOCKETS_IO_NAMES removed that declaration.

This adds sys/ioctl.h file and the missing declaration.
Also adds missing includes in vfs.c.
