  Removed files:
    lib/libc/stdlib      putenv.c setenv.c 
  Log:
  Significantly reduce the memory leak as noted in BUGS section for
  setenv(3) by tracking the size of the memory allocated instead of using
  strlen() on the current value.
  
  Convert all calls to POSIX from historic BSD API:
   - unsetenv returns an int.
   - putenv takes a char * instead of const char *.
   - putenv no longer makes a copy of the input string.
   - errno is set appropriately for POSIX.  Exceptions involve bad environ
     variable and internal initialization code.  These both set errno to
     EFAULT.
  
  Several patches to base utilities to handle the POSIX changes from
  Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
  instead of putenv().
  
  New regression module for tools/regression/environ to test these
  functions.  It also can be used to test the performance.
  
  Bump __FreeBSD_version to 700050 due to API change.
