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.

15b26f8841 VFS: esp_vfs_select() needs to be callable from concurrent tasks 
This fix is for compatibility with lwip_select(). It moves the lock to
UART which is the only VFS driver which is implemented and is not
"thread-safe".

e6ae121f41 VFS select: Correct reseting of socket FDs

from the fd_sets before passing these fd_sets forward to the socket
select function.

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.

3ebf7923d3 lwip: Route LWIP socket POSIX I/O functions via IDF VFS layer 
No more conflicts between LWIP & newlib read(), write(), fcntl(), etc.

select() still only works if all of the fds are sockets.

2ccfe3da96 vfs: fix opendir of a filesystem root directory 
Previously opendir("/data") would fail if filesystem with "data" prefix
was registered in VFS, while opendir("/data/") would succeed.
This change fixes handling for the former case and adds relevant tests.

53d5c5f668 vfs, fatfs: fix support for two FATFS instances (SD and flash) 
- fix null pointer dereference in VFS when VFS implementations are added
  and removed in different order

- vfs_fat_sdmmc, vfs_fat_spiflash: pass correct drive to mkfs
  (previously it would always do mkfs in the first drive)

- add test case

- fix build system test failure
- use posix off_t instead of newlib internal _off_t
