Removed the static m_getfld() state instance and replaced

with functions for callers to create and destroy their own
instances.  This also allows inc, msh, and pick to call
m_getfld() with an initial file stream position other than 0.

There is now a global state instance so that scan can call
m_unknown() on maildrop files.  It'd be nice to get rid of
that.

-Restrictions
-============
-m_getfld() is restricted to operate on one file stream at a time
-because of the retained state (see "State variables" above).  And the
-first call to m_getfld() on that file stream requires that the read
-pointer be at the beginning of the file (ftell() of 0).
-
-Current usage
-=============
-The first call to m_getfld() on a file stream is with a state of FLD.
-Subsequent calls provide the state returned by the previous call.
-Therefore, given the Restrictions above, the state variable could be
-removed from the signature and just retained internally.
