spi test: Prime the flash cache before each test to minimise flash cache misses.
VFS performance test: Increase the number of runs to minimise influence of an isolated bad run.
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".
When using multiple sockets, some of them could be incorrectly removed
from the fd_sets before passing these fd_sets forward to the socket
select function.

* Philosophical: "explicit is better than implicit".
* Practical: Allows useful errors if invalid directories given in components as the defaults aren't
always used. Also trims the -I path from a number of components that have no actual include
directory.
* Simplifies knowing which components will be header-only and which won't
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.
vfs_uart used same locks for read and write operations on a single UART.
If read operation was blocking (i.e. carried out via UART driver), the
lock was held by reading task until it received a line. During this time,
other tasks trying to write to the same UART would get blocked.
This change introduces separate read/write locks, and adds a test.
Another vfs_uart test if fixed (it was disabled since the
CONFIG_NEWLIB_STDOUT_ADDCR option was removed).
Previously VFS driver for UART could only use simple non-blocking
functions to read from and write to the UART. UART driver provides more
complex blocking and interrupt-driven functions, which can be used
instead.
This commit adds optional support for using UART driver's functions.
Also added is a more flexible mechanism for configuring newline
conversion rules on input and output.
This commit also fixes a bug that all UARTs shared one static variable
used as a character buffer in newline conversion code. This variable is
changed to be per-UART.
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.
