This catches output dependency violations, e.g. two threads doing a
read-modify-write without synchronization.
New struct emptypedstr member seqno. Make sure all members of unit
empobj_storage share it. Set it in ef_blank() and ef_set_uid(), step
it in ef_write(). fairland and files don't use ef_set_uid(); need to
set it manually in files.c's main() and file_sct_init().
Factor do_read() out of fillcache() to make it available for
new get_seqno().
Make sure all members of unit empobj_storage share it.
Add matching timestamp member to struct comstr, struct empobj, struct
gamestr, struct lonstr, struct natstr, struct nwsstr, struct trdstr,
struct trtstr. The timestamp isn't yet set for these. To be fixed.
Move the timestamp member to the right place in struct lndstr, struct
loststr, struct realmstr, struct nukstr, struct plnstr, struct sctstr,
struct shpstr.
Make sure all members of unit empobj_storage share uid in addition to
ef_type.
Add matching uid member to struct gamestr, struct natstr and struct
sctstr, and set them.
Swap struct empobj members uid and own to make that easier, and update
struct comstr, struct lndstr, struct lonstr, struct loststr, struct
nwsstr, struct nukstr, struct plnstr, struct realmstr, struct shpstr,
struct trdstr, struct trtstr accordingly.
Note that the uid isn't properly set for struct nwsstr, struct lonstr,
struct trdstr, struct comstr and struct loststr. To be fixed.
other. Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special). New header types.h to
help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
(sect_ca, ship_ca, land_ca, plague_stages, empfile):
Add plague stages symbol table.
(treaty_ca, loan_ca, agreement_statuses, empfile):
Add agreement status symbol table.
Combine treatystatuses (TS_FREE, TS_SIGNED and TS_PENDING)
and loan statuses (LS_FREE, LS_SIGNED and LS_PENDING)
into a single agreement status.
(pchr_ca, level, empfile): Add packing symbol table.
