MFC r231949:
Fix found places where uio_resid is truncated to int.
Add the sysctl debug.iosize_max_clamp, enabled by default. Setting the
sysctl to zero allows to perform the SSIZE_MAX-sized i/o requests from
the usermode.
MFC r232493:
Remove unneeded cast to u_int. The values as small enough to fit into
int, beside the use of MIN macro which performs type promotions.
MFC r232494:
Instead of incomplete handling of read(2)/write(2) return values that
does not fit into registers, declare that we do not support this case
using CTASSERT(), and remove endianess-unsafe code to split return value
into td_retval.
While there, change the style of the sysctl debug.iosize_max_clamp
definition.
MFC r232495:
pipe_read(): change the type of size to int, and remove signed clamp.
pipe_write(): change the type of desiredsize back to int, its value fits.

MFC r227342. Note that the original commit message, reproduced below, has
error. The final sentence should read "*without* CTF data".
The in-kernel CTF parser caches the result of its first attempt to parse
CTF data from a module. On subsequent attempts to retrieve CTF data for
a module, return an error if there no CTF data.
This fixes a panic if you try to enable fbt probes on a module with CTF
data twice.
