according to context, to make `lstat * ?type#spy&spy>1' work. Closes
bug#825363, #905809, #905814 and #922968.
(nsc_type, packed_nsc_type, nsc_cat, packed_nsc_cat, nsc_flags): New.
(valstr): New. Old code encoded values in type long, which was
somewhat hard to read and could only support signed integer values.
(nscstr): Redesign. Use valstr. Typed operator.
(castr): Split ca_code into ca_type, ca_flags, ca_off. Tables
changed.
(nstr_comp, nstr_exec): Redesign and rewrite. Callers changed. They
used the old design incorrectly, which let players smash the stack
by supplying more than NCOND conditions.
(encode, nstr_comp_val, decode, nstr_exec_val): Rename, redesign, and
rewrite. Callers changed.
(nstr_coerce_val): New.
(var_ca, sect_ca, ship_ca, land_ca): Checking both var_ca[] and the
object's ca complicates proper recognition of unique abbreviations.
Copy contents of var_ca[] into the ca of objects, remove var_ca[].
(surv): Reject values with category other than NSC_OFF and types that
can't be coerced to NSC_LONG. Old code happily passed values with
category NSC_VAL to code_char(). The previous version interpreted
them correctly, but earlier versions interpreted them as NSC_OFF, then
logged `bad type in decode: 0' and evaluated them into zero.
(code_char): Used to test category NSC_VAR to decide whether to
display tens or hundreds. NSC_VAR no longer exists. Test type
instead. Makes more sense anyway.
Simplify. Split into member sct_che (number) and sct_che_target.
Users changed.
(get_che_cnum, set_che_cnum, get_che_value, get_che_value): Che
encoding/decoding functions; remove.
(CHE_MAX): Move from var.h to sect.h.
(prsect, doland): Print / edit the new field.
To save space, the ancients invented `variables': a collection of
key-value pairs, missing means zero value, space for `enough' keys.
This complicates the code, as assigning to a `variable' can fail for
lack of space. Over time, `enough' increased, and for quite some time
now `variables' have been *wasting* space. This changeset replaces
them, except in struct mchrstr, struct lchrstr and struct pchrstr,
where they are read-only, and will be replaced later. It is only a
first step; further cleanup is required. To simplify and minimize
this necessarily huge changeset, the new item[] arrays have an unused
slot 0, and the old variable types V_CIVIL, ... are still defined, but
must have the same values as the item types I_CIVIL, ...
(genitem_ca, ship_ca, plane_ca, land_ca): Remove selector "sell".
(comstr, trdstr): Members trd_price, com_price have no effect. Use
them instead of trd_maxprice, com_maxprice and remove the latter.
(commodity_ca, trade_ca): Remove selector "maxprice".
its code is obviously not in working order. Remove.
(minmult, maxmult, configkeys): Unused configuration parameters,
remove.
(tradedesc): Remove code related to mult that had no effect.
(multread, commread, commwrite, commamt, commset, multset, commprice):
Dangerous, because code bypasses ef_read() & friends, remove.
(diss): Commodity cleanup uses the above, remove. Command is disabled
and unlikely to work anyway.
loan_ca, news_ca, lost_ca, commodity_ca, trade_ca, nat_ca, map_ca):
NSC_OFF was lost during Empire3, rendering the codes confusing and
harder to use. Tack it back on.
(encode, code_char): No need to fool around with NSC_OFF anymore.
tennames, numstr): Replace by static local variables in their only
user.
(relates): Move from global/misc.c to common/nat.c.
(att_mode): Move from global/misc.c to subs/attsub.c.
instead of declaring them all over the place. This uncovered type
errors:
(s_p_etu, adj_update): Defined long, sometimes declared int. Kills
big endian machines where sizeof(long) != sizeof(int). Change to
int.
(set_option, delete_option, optstrset, intset, floatset, doubleset,
longset, optionset, optiondel, worldxset): Change linkage to static.
EMPPATH() to use EMPDIR. This avoids triggering MSVC bugs, and drops
support for traditional, pre-ISO cpp. Closes#753935.
(gamedir, lostfil, playerbin, updatebin): Unused, remove.
