- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.

Style fixes.
Remove DBL_DIG, DBL_MIN, DBL_MAX and their FLT_ counterparts, they
were marked for deprecation ever since SUSv1 at least.
Only define ULLONG_MIN/MAX and LLONG_MAX if long long type is
supported.
Restore a lost comment in MI _limits.h file and remove it from
sys/limits.h where it does not belong.

Properly define CHAR_MIN/CHAR_MAX taking into account whether or
not __CHAR_UNSIGNED__ is defined.

Fix a typo in UINT_MAX definition.

Add a new sys/limits.h file which in turn depends on machine/_limits.h
to get actual constant values. This is in preparation for machine/limits.h
retirement.
