Add paragraph that defines jitter. Fix a few minor typos. Fix
incorrect reStructuredText formatting for bulletpoints (they were
being rendered like 2nd level bulletpoints).

Add zerolatencyinterrupts.rst to the TOC, which I forgot to do in PR
# 9302.
- Linux: What inside /etc/hosts comes first.
- NuttX: Even if we write a domain in /etc/hosts, we still use DNS
result instead of hosts lines. This patch change this behavior.

Notify the compiler that the condition flag has changed to prevent the
compiler from optimizing and reordering instructions, which may cause exceptions.

USB drivers should not try control devices in the usbhost_disconnected
function. The control endpoint is NULL at this point because the device
has already been disconnected.
Before this change, the hub driver crashed when the child called
usbhost_hubpwr after the parent had already deactivated the control
pipe and set hport->ep0 to NULL.
When do socket bind, if the connection domain is not equal to the bound address type, this will cause the stack-buffer-overflow.

Signal must be masked when it is delivered to a signal handler per:
https://pubs.opengroup.org/onlinepubs/007904875/functions/sigaction.html:
When a signal is caught by a signal-catching function installed by sigaction(), a new signal mask is calculated and installed for the duration of the signal-catching function (or until a call to either sigprocmask() or sigsuspend() is made). This mask is formed by taking the union of the current signal mask and the value of the sa_mask for the signal being delivered [XSI] [Option Start] unless SA_NODEFER or SA_RESETHAND is set, [Option End] and then including the signal being delivered. If and when the user's signal handler returns normally, the original signal mask is restored.
Any action queued for that signal while the signal is masked should be deferred. It should go into the group pending signal list and should not be processed until until the signal is unmasked (which should occur when the signal handler returns).
1 Gbit W25Q01JV flash uses two 512 Mbit dies. This requires specific
operations in the driver in order to support the entire 1 Gbit region.
This commit adds dual die support for W25Q01JV flash.
Generally the driver has to switch active dies when die specific read from
status register is required (therefore before read, write, erase and when
checking if write status register was successful).

The "CONFIG_APPS_DIR" generated in .config has double quotes and is not recognized as a path by most make systems. This commits removes these double quotes to make the compile successfully.
ESP32 and ESP32-S3 should use the ROM-defined versions of the libc
in flat build and, when building the protected mode, in the kernel.
The ROM-defined version of the libc functions can't be used in the
userspace, however, because it isn't allowed to access the memory
region in flash directly from the userspace. That being said,
`LIBC_PREVENT_STRING_KERNEL` should be selected to avoid building
any implementation of the libc, being the ROM-defined versions
linked instead.
NuttX's software implemented version of the libc will be built in
the userspace. Also, the assembly-defined version of some of the
libc functions (`XTENSA_xxx`) may also be selected to be used in
the userspace.
Add the `LIBC_PREVENT_STRING_KERNEL` and `LIBC_PREVENT_STRING_USER`
that are meant to be selected by the chip if no libc implementation
is going to be built. If selected, neither NuttX's software version
of the libc nor any architecture-specific implementation will be
built in the kernel or in the userspace, respectively. In this
case, the linker may provide a ROM-defined version of the libc
functions instead.
if multiple threads are doing serial read/write at the same time,
the driver will only wake up one of the thread, which will cause
other threads fail to be woken up in time and cause blocking
