7c1fc1c567 wplua: table_to_properties: use luaL_tolstring to do string conversions 
The advantage is that luaL_tolstring behaves the same as the native lua
tostring() function, while lua_tostring() does not. In particular, boolean
values are converted properly to "true" and "false" now, while they were
not converted with lua_tostring()

Add a unit test too

e92351b23b wplua: gvariant_to_lua: convert dictionary keys to integers if possible 
When we convert from a lua table to a GVariant dictionary, it is not
possible to maintain the hybrid string & integer keys approach that Lua
has for tables, so we convert all keys to strings and a table becomes a{sv}

When we convert back from a{sv} to a table, it is desirable to get back
the integer keys wherever possible.

The use case is to pass "arrays" (i.e. tables with integer keys) from
the configuration files to the lua scripts, without losing the properties
of the "array"

e0f1c8710f daemon: add a mode to execute lua scripts from the command line 
This can be useful for quick testing of scripts, or to build small
utilities that do something in pipewire utilizing our lua API

94d527e187 wplua: add flags to modify the sandbox behavior 
with ISOLATE_ENV, it isolates the global environment between scripts
just like it did before; without it, it uses a common environment

with MINIMAL_STD, it restricts even further the available library
functions; useful for configuration files that don't need to do
actual scripting, just to define some tables
