* Makefile:
  . Hook e_lgammal[_r].c to the build.
  . Create man page links for lgammal[-r].3.

* Symbol.map:
  . Sort lgammal to its rightful place.
  . Add FBSD_1.4 section for the new lgamal_r symbol.

* ld128/e_lgammal_r.c:
  . 128-bit implementataion of lgammal_r().

* ld80/e_lgammal_r.c:
  . Intel 80-bit format implementation of lgammal_r().

* src/e_lgamma.c:
  . Expose lgammal as a weak reference to lgamma for platforms
    where long double is mapped to double.

* src/e_lgamma_r.c:
  . Use integer literal constants instead of real literal constants.
    Let compiler(s) do the job of conversion to the appropriate type.
  . Expose lgammal_r as a weak reference to lgamma_r for platforms
    where long double is mapped to double.

* src/e_lgammaf_r.c:
  . Fixed the Cygnus Support conversion of e_lgamma_r.c to float.
    This includes the generation of new polynomial and rational
    approximations with fewer terms.  For each approximation, include
    a comment on an estimate of the accuracy over the relevant domain.
  . Use integer literal constants instead of real literal constants.
    Let compiler(s) do the job of conversion to the appropriate type.
    This allows the removal of several explicit casts of double values
    to float.

* src/e_lgammal.c:
  . Wrapper for lgammal() about lgammal_r().

* src/imprecise.c:
  . Remove the lgamma.

* src/math.h:
  . Add a prototype for lgammal_r().

* man/lgamma.3:
  . Document the new functions.

Modify cpuset_setithread() to take a CPU ID as an integer, not a char.

We're going to end up having > 254 CPUs at some point.
Ensure the correct software IPv4 hash is done based on the configured
RSS parameters, rather than assuming we're hashing IPv4+UDP and IPv4+TCP.
