cb08c2cc83 Add some FEATURE macros for various GEOM classes. 
No FreeBSD version bump, the userland application to query the features will
be committed last and can serve as an indication of the availablility if
needed.

b53a1cf306 Don't pass error value pointer to g_read_data(9) at all if we don't 
have any use of it.

8a4a44b5aa Check for g_read_data(9) errors properly: 
o The only indication of error condition is NULL value returned by
  the function;

o value pointed to by error argument is undefined in the case when
  operation completes successfully.

d2bae332d6 Remove the absolute count g_access_abs() function since experience has 
shown that it is not useful.

Rename the relative count g_access_rel() function to g_access(), only
the name has changed.

Change all g_access_rel() calls in our CVS tree to call g_access() instead.

Add an #ifndef BURN_BRIDGES #define of g_access_rel() for source
code compatibility.

e65ab0f83f Use g_slice_spoiled() rather than g_std_spoiled(). 
Remember to free the buffer we got from g_read_data().

3924ad705e Time has run from the "run GEOM in userland" harness, and the new regression 
test is built to test GEOM as running in the kernel.

This commit is basically "unifdef -D_KERNEL" to remove the mainly #include
related code to support the userland-harness.

c138fec0b5 Premptively change initializations of struct g_class to use C99 
sparse struct initializations before we extend the struct with
new OAM related member functions.

ddfa3cce05 Add some comments about the deficiencies of this module. I had hoped to get 
around to addressing them some more, but Real Life (tm) has gotten in the
way.

6be2e1dd37 Correct a comment. GEOM modules do not create /dev entries. They create 
providers.

a6fff888c3 Add the GEOM module that makes volume labels useful. A kernel compiled with 
this will cause volume labels to be exposed in /dev/vol/<volname>. Currently,
there is no conflict resolution if more than one FS has the same volume name.
