Add kvm_dump_header and implement kvm_dump_wrtheader on top of it.
...
This function allows the caller finer control of how the writes happen
and doesn't force stdio as interface. Optimise clear_gap a bit to not
fill the gap byte-wise. Bump minor version of libkvm.

1. Eliminate some unnecessary to kvm_{m,re}alloc.
...
2. Don't malloc/free procbase/procbase2/lwpbase continuously. Keep track
of the size, and only do it if necessary.
3. Write a macro to malloc/realloc and set the size of members so that it
is done correctly. Previous open coded version in kvm_file.c always
set the length, which is incorrect.
4. Remove bogus check against INT_MAX.
5. use NULL to initialize pointers instead of 0.
