com32/chain/partiter: make iterators not autofree after fin/err
This patch changes iterator behaviour to not free themselves
automatically after finished iteration or error. This allows
us to be able to always:
- check their status through ->status field
- access last valid data
It will allow simplification of pentry_mangle() function in
further commits.

chain/chain.c: add "raw" handover
This adds a possibility to create an area resembling proper handover,
when booting mbr of some media. If we have custom/special booting code
always expecting handover, this would allow us to boot it from the 1st
sector as well.

chain/utility.c: Adjust lba2chs
This tiny patch adjusts how lba2chs() deals with unknown geometries.
Instead of returning max values of "typical" geometries, it returns
chs values calculated from them.

chain module: bugfixing and cosmetics
Bugs:
- one introduced ages ago - find_by_* functions should be tested vs. <0
for failure
- one introduced by
579f15c7c456c - it accidentally blocked too much
when testing for ',' in drive/partition option parsing
- one introduced by
d4d713c9ccfe0 - sone machines / VMs seem to set
@40:75 just 1, regardless of amount of fixed disks available

chain module: setbpb changes, bss & bs options, bugfixes
Generic function detecting BPB type (7 versions) have been added.
set{hid,geo,drv} have been replaced by single setbpb option, using
mentioned function to make more precise decisions what to update where.
Full BSS and BS emulation has been added, also employing BPB detection.
Some logic/flow changes in chain's main(). There was also a bug, in
which backup sector was populated with wrong data.
Appropriate documentation updates.
