0357fa2632 Restrict locale settings to the file they occur in
This prevents LANG= in an included file from affecting the interpretation
of month and day names in the including file.

Make the internal pre-processor accept white space between the "#" at
the start of the line and the keyword for better compatibility with cpp.

Add support for the cpp keywords #warning and #error.

2ceb17a8be Add regression tests for conditions and comments
Fix one case where #else was not corerctly processed and simplify the
conditions logic.

Fix parsing of day and month names in the locale specified in the calendar
file. The previous version would expect those names to match the locale of
the user.

Mention that comments are now correctly processed and that // is supported
in addition to /* ... */.

f1560bd080 Consistently print calendar dates in the locale of the user
Calendar files that specify LANG=... to specify their character encoding did
also set the date format defined for that locale, resulting in output like:

Nov  4 	Gabriel Faure dies from pneumonia in Paris, France, 1924
 4 nov. 	N'oubliez pas les Charles !

After this commit the output is always printed in a consistent format
according to the user's current locale, e.g.:

Nov  4 	Gabriel Faure dies from pneumonia in Paris, France, 1924
Nov  4 	N'oubliez pas les Charles !

I'll open a review asking for opinions whether this format change should
be merged to -STABLE.

8e8c5da47f Improve calendar file parsing and consistency tests
Add line number information to more warning and error messages.
Detect #else and #endif without corresponing #ifdef/#ifndef as error.
Detect missing #endif at end of file and print warning but continue.

Support for #undef has been added to reverse the effect of a prior #define.
It is no error if the argument value has not been defined before.

These changes may cause error aborts on malformed input files (e.g. with
spurious #else or #endif), but no such errors exist in the calendar files
in the FreeBSD base system and the calendar-data port and all tests pass.

More tests will be added in a follow-up commit to detect regressions that
might affect the newly added features.

This commit ends a series of updates that enhance the pre-processor and
make it behave much more like prior versions of the calendar progarm that
called cpp to pre-process the data files.

ddad3a3875 Print calendar entries in the order they occur

0f352f4e25 Re-implement comment parsing missing in the internal pre-processor
The internal pre-processor ignored lines that did not parse a calendar
entries, but did not support multi-line comments in the way the external
cpp did.

The calendar files distributed with the base system (now in a port) do
use comments, though.

Implement comment processing for single-line (//) and multi-line comments
(/* */) with same semantics as in a standard C pre-processor.

All tests pass with this version, but there are no tests that specifically
verify comment processing.

3fa2a149d6 Fix calendar -a processing of files included in the user's home directory
The existing code performed a chdir() into the home directory, but the
parser fell back to using the invoking user's home directory as the base
directory for the search for an include file.

Since use of the -a option is limited to UID==0, the directory searched
was typically ~root/.calendar, not the .calendar directory of the user
whose file is being processed.

19b5c30754 Add support for nested conditionals
The previous behavior was to support nested #ifdef and #ifndef, but to
return to unconditional parsing after the next #endif, independently of
the number of previously parsed conditions.

E.g. after "#ifdef A / #ifdef B / #endif" the following lines were
unconditially parsed again, independently of A and/or B being defined.

The new behavior is to count the level of false conditions and to only
restart parsing of calendar entries when the corresponding number of
#endif tokens have been seen.

In addition to the above, an #else directive has been added, to toggle
between parsing and ignoring of the following lines.

No validation of the correct use of the condition directives is made.
#endif without prior #define or #ifndef is ignored and #else toggles
between parsing and skipping of entries.

The MFC period has been set to 1 month to allow for a review of the
changes and for a discussion, whether these modifications should not
be merged at all.

No correct input file is parsed differently than before, but if calendar
data files are published that use these new features, those data files
will not parse correctly on prior versions of this program.

e0e29f9425 Fix off-by-one error in processing of #ifdef lines
The convention in this program is to parse the line immediately starting
after the token (e.g. #defineA and #ifdefA define respectively look-up "A"),
and this commit restores this behavior instead of skipping an assumed
white-space character following #ifdef.

2939897921 Fix parsing of #ifdef in calendar files
There was code to process an #ifndef tokens, but none for #ifdef.
The #ifdef token was mentioned as unsupported in the BUGS section,
but no reason was given and I do not see why it should stay omitted.

Misleading information in The BUGS section of the man-page regarding
the maximum number of #define and #include statements supported has
been removed. These limits might have applied to a prior version of
this program, but do not seem to apply to the current implementation.

I have not tried to test for the existence of the limits, but the
include file processing just recursively calls the parser (without
counting the recursion depth) and the stringlist functions do not
impose a limit on the number of entries.

c77b04884c Udpate calendar man-page to mention the search path added in r366962.
Calendar files in /usr/lcoal/share/calendar take precedence over files in
the base system. They can be provided by a port or package, but since such
a port has not been committed, yet, no specific port name is suggested.

In fact, multiple ports could exist (e.g. per locale) without conflicting
with each other.

34b38e1245 Add search of LOCALBASE/share/calendar for calendars supplied by a port.
Calendar files in LOCALBASE override similarily named ones in the base
system. This could easily be changed if the base system calendars should
have precedence, but it could lead to a violation of POLA since then the
port's files were ignored unless those in base have been deleted.

There was no definition of _PATH_LOCALBASE in paths.h, but verbatim uses
of /usr/local existed for _PATH_DEFPATH. Use _PATH_LOCALBASE here to ease
a consistent modification of this prefix.
