For the jq_state used by the jq utility, the JQ_LIBRARY_PATH attribute
will always be set, but, in general, it is possible that it might not
be.
If it is not set, jq_get_lib_dirs() will return jv_invalid().
That is not good, because some code in linker.c expects it to always
returns an array.
This patch makes jq_get_lib_dirs() return an empty array if
JQ_LIBRARY_PATH is not set to prevent problems.
This issue made OSS fuzz trigger failed assertions every time it tried
to compile a script that uses "include".

Although #2839 fixed the overflow of exponent subtraction,
there still is possibility of overflow in the `D2U` macro.
This patch fixes the overflow in the `D2U` macro, and also
truncates the maximum digits to `DEC_MAX_DIGITS`.

This reverts commit 086a156ec389de167edc72e8bd1752984b117349.
This commit leads to negative indexing wraps twice.

clang complained that this is deprecated in all versions of standard C,
and unsupported in C2x.

The decNumber library subtracts the exponents of two numbers,
we make sure to limit the number of digits not to make it overflows.
Since the maximum adjusted exponent is `emax` and the minimum is
`emin - digits + 1`, we follow `emax - (emin - digits + 1) <= INT32_MAX`.

This reuses the existing `block_list_funcs` capability and adds an extra field on the `modulemeta` output, called `defs`, containing that list of functions.

* Build windows 64bit binary using UCRT64
Is the default and recommended msystem setting. Will produce
binaries that are compatible with windows 10 and later.
Also run tests for 32bit build.
Related to #2831
* Use jq -b in tests/shtest
* Add Windows strptime
* Make Windows-optional tests not run on Windows again

This patch removes the weird behaviour of jv_invalid_with_msg(jv_null())
that returns jv_invalid() (i.e. empty), instead of a boxed jv_null().
The previous behaviour of null|error was obviously unintentional, and
allowing is jv_invalid_with_msg() to return values on which you can't
call jv_invalid_get_msg() is only error prone.

This patch exports all the binary operator builtins functions from
builtin.c and uses them for constant folding in the parser, allowing
constant folding to work will all kinds and combinations of constants.
Now string*number, $ARGS+$ARGS, string/string, etc will also be
constant folded and the implementation of constant folded operators and
runtime operators will be the same.
And thanks to the new ERRORK bytecode operation, errors are constant
folded too! (e.g. 1 / 0 [] * {} etc)

Use a StringStart component that is either FORMAT QQSTRING_START or
QQSTRING_START instead of having two similar rules for String.
This is simpler and avoids having to use an untyped mid-rule action
component to copy FORMAT at the top of the stack before QQString, and
having to use jv_free($<literal>3) instead of jv_free($1) just to make
bison not complain about the "unused" mid-rule component.

For some reason, the env vars are set correctly without refering the variable in `matrix` case-sensitvely:
```
2023-08-01T05:05:58.4626090Z env:
2023-08-01T05:05:58.4626367Z AR: arm-linux-gnueabihf-ar
2023-08-01T05:05:58.4626690Z CHOST: arm-linux-gnueabihf
2023-08-01T05:05:58.4626961Z CC: arm-linux-gnueabihf-gcc
2023-08-01T05:05:58.4627332Z CPP: arm-linux-gnueabihf-cpp
2023-08-01T05:05:58.4627662Z CXX: arm-linux-gnueabihf-g++
```
For clarify, we update them to match the definitions. Besides, `CXX` is
not needed and removed.

Previously constant folding of zero division (e.x. 1/0) produces a
compile error. This was incorrectly implemented by checking if the
division result is infinite, so produces wrong results compared to the
query where no constant folding is processed (e.x. 1e308/0.1). This
patch delays the operation when the divisor is zero. This makes the
results more consistent, but changes the exit code on zero division from
3 to 5. Also 0/0 now produces the zero division error, not NaN.
This patch also fixes the modulo operation. Previously constant folding
logic does not take care of the % operator, but now it folds if the both
dividend and divisor are safe numbers to cast to the integer type, and
the divisor is not zero. This patch also fixes some code that relies on
undefined cast behaviors in C. The modulo operation produces NaN if
either the dividend or divisor is NaN.

You only need to specify the return type in a function pointer
declaration in C.
If you use () in the declaration, the function pointer can be called
with any arguments, and the type of the arguments is decided for each
function call based on the types of the arguments used for the call.
(To declare a function pointer for a function with no arguments, you use
`(void)'.)
Since all the cfunction structs have a fptr that points to a functions
that return jv, not void, we can we can just declare cfunction.fptr as
jv (*)() and avoid having those annoying and technically not C-standard
compliant casts everywhere.

We now have an official Discord server and most maintainers are hanging
out there. It would be a good idea to redirect questions to Discord.
