(banfil, authfil, timestampfil): Make file names relative to DATADIR.
(main): emp_server and files change to the data directory. fairland
has to write newcap_script to the initial current directory, so it
keeps it and makes file names relative to DATADIR absolute.
(fixup_files): Nothing to do, remove. This fixes the following bug:
fixup_files() formed file names by appending ep->name instead of the
base name of ep->file to datadir. Thus, fixup_files() changed file
names even when datadir had the compiled-in value. When emp_config()
couldn't open econfig, it failed to call fixup_files(), and different
file names got used. Note that with this revision the file names
revert to the names used before fixup_files() was introduced. Closes
#1146080.
(print_config): Printing file names as comments is not really useful,
remove.
(otherfiles, ofiles): Unused, remove.
(emp_config, main): Previously, pconfig had to call emp_config() even
when it didn't want to read econfig, just to run fixup_files(). This
is no longer necessary. Simplify.
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, ...
thread entrypoints:
(lwpSelect, shutdown_sequence): Parameters didn't match thread entry
point prototype.
(lwpEntryPoint): Arguments didn't match thread entry point prototype.
Change linkage of functions without prototype declaration to static
where possible.
Remove some superflous declarations, replace others by suitable
includes.
