When dumping a string, adding 2 to its size may overflow a size_t for
external strings, which may not have a header. (Adding 1 is Ok, because
all strings end with a '\0' not included in their size.) The new method
for saving NULL strings code them as a repeated string, using the
reserved index 0.
Dump uses varints also for integer constants2025-06-13T17:14:50+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-06-13T17:14:50+00:00urn:sha1:0cecf1ab6d76e6a7d200fb01bdd999b61835fe21
Unlike sizes, these constants can be negative, so it encodes those
integers into unsigned integers in a way that keeps small numbers
small.

The structure 'AbsLineInfo' is hard-dumped into binary chunks, and
it comprises two 'int' fields.
Added gcc option '-Wconversion'2024-07-27T16:32:59+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-07-27T16:32:59+00:00urn:sha1:0acd55898d0aaae8dbc14c8a1bc1e3bdffc8701b
No warnings for standard numerical types. Still pending alternative
numerical types.
Cleaning of llimits.h2024-06-20T16:43:33+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-06-20T16:43:33+00:00urn:sha1:55ac40f859ad8e28fe71a8801d49f4a4140e8aa3
Several definitions that don't need to be "global" (that is, that
concerns only specific parts of the code) moved out of llimits.h,
to more appropriate places.
'luaH_get' functions return tag of the result2024-03-21T14:23:21+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-03-21T14:23:21+00:00urn:sha1:0593256707ceddb1bc9cd4b25b822a7fbcfedd66
Undoing previous commit. Returning TValue increases code size without
any visible gains. Returning the tag is a little simpler than returning
a special code (HOK/HNOTFOUND) and the tag is useful by itself in
some cases.
'luaH_get' functions return 'TValue'2024-03-18T18:56:32+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-03-18T18:56:32+00:00urn:sha1:ce6f5502c99ce9a367e25b678e375db6f8164d73
Instead of receiving a parameter telling them where to put the result
of the query, these functions return the TValue directly. (That is,
they return a structure.)
Removed type 'varint_t'2024-03-13T12:16:51+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-03-13T12:16:51+00:00urn:sha1:cc2b66c85687b095e68304c010b59851ca4093e1
size_t should be big enough to count the number of strings in a dump.
(And, by definition, it is big enough to count the length of each
string.)
