PWM drivers usually supports dead time generators that automatically
insert output activation delay for complementary PWM outputs. This
is usefull for some control purposes as control of H bridge for example.
This commit adds an application to driver interface that can be used
to set up those delays (if supported by the selected architecture)
directly from the application. The set up remains the same as for duty
cycle value.
The whole addition is by default disabled. It can be enabled by config
option PWM_DEADTIME.

Use lib_get_stream() to fetch stdin/stdout/stderr,
since is more easy to works with other language by function call
than export native C structure memory layout.

* 32-bit time_t should be unsigned because otherwise it wraps too
soon. (in 2038)
* 64-bit time_t should be unsigned because it should be consistent
within NuttX.
* While signed time_t seems more popular among other OSes, the
consisitency within NuttX outweighs, IMO.

Generic drivers shoud not use architecture related config options like
CONFIG_SAMV7_PWM. This commit adds PWM pin overwrite under generic
configuration option CONFIG_PWM_OVERWRITE.
Now the overwrite can be used on other architectures as well or can be
completely disabled for SAMv7.

Do not allow a deferred cancellation if the group is exiting, it is too
dangerous to allow the threads to execute any user space code after the
exit has started.
If the cancelled thread is not inside a cancellation point, just kill it
immediately via asynchronous cancellation. This will create far less
problems than allowing it to continue running user code.
SOCK_CTRL is added to provide special control over network drivers
and daemons. Currently, SOCK_DGRAM and SOCK_STREAM perform this control,
but these use socket resources. In the case of usersocket in particular,
this is a waste of the device's limited socket resources.
The version information basically uses 20 characters for date and time,
which is small enough to specify an arbitrary version string. Therefore,
increase the buffer a little.
caculate blk address when mempool_multiple_free
have a bug. need a real blocksize to caulate the
memory address.

Without this POSIX-compatible definition, support for nativesockets module in Nimlang is problematic.
