defines, import these defines into plague.h, drop var.h and include
plague.h where appropriate.
Remove some 'register' keywords at the same time.
No functional changes.
PRI_LBUILD): Turn macros into enumeration constants. Value
SCT_MAXDEF+1 was previously unused; use it.
(PRI_MAX): New; replacing the horrible SCT_MAXDEF+8.
(show_sect_build): Simply examine all sector types, don't skip the
first five. The code ignores them just fine.
(show_sect_build, show_sect_stats, show_sect_capab): Don't try to show
sector types beyond SCT_MAXDEF. The table has some empty extra slots,
for whatever reasons; no use examining them.
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, ...
effect. Replace calls by struct assignment where possible. Replace
clear buffer, copy string to buffer by strncpy(). Use assignment to
clear when that's clearer. Replace overlapping copy through bounce
buffer by memmove(). Replace rest by standard memset() and memcpy().
Also use sizeof() instead of literal array sizes for robustness, and
instead of symbolic array sizes for clarity.
