Untangle lib/fsm.c and lib/cpio.c Create cpio_t data type that holds the underlaying FD_t instance Move padding and position handling and trailer generation into cpio.c Use only one buffer in the fsm (merging the read and write buffer) Replace the FSM_EAT, FSM_POS, FSM_PAD, FSM_DREAD, FSM_DWRITE states with cpio functions Prepend "rpm" to the cpio function names

Stop abusing enum typedefs for bitfield types - Enums are fine for defining the bitfield flags, but the bitfield itself is not an enumeration. Add a separate typedef on "rpmFlags" type (presenting a bitfield of flags) for all of these. Compilers hardly care, but the typedefs give a nice visual clue for us humans using these flags far away from ho^H^H definitions.

Clean up progress callbacks in fsm/psm machinery - Move notifications from fsm to psm side for sanity and symmetry, psm already has members to hold the callback state. - Replace PSM_NOTIFY "state" with a helper function that both fsm and psm itself use (except for error callbacks which are a bit different) - Init psm->total early, this doesn't change and can now be used to refer to "all done" value whatever it happens to be, instead of magic "100" values etc. - Packages with no files are now handled through the same path as everything else from progress reporting pov, we just skip calls to fsm if there are no files. - Issue stop callbacks for install as well. While INST_CLOSE_FILE can be (and is currently) used to detect this condition, its conceptually an entirely different thing. - Fix erasure callback parameters, they were reversed (starting from total and ending with 0, ehh...)
