59c88f846d Broadening the use of branch hints
More uses of macros 'likely'/'unlikely' (renamed to
'l_likely'/'l_unlikely'), both in range (extended to the
libraries) and in scope (extended to hooks, stack growth).

61a4e64a66 Back to old encoding of versions in binary files
(Undoing part of commit f53eabeed8.)  It is better to keep this encoding
stable, so that all Lua versions can read at least the version of a
binary file.

a901c505ab Fixed warning about casts between function pointers
gcc now warns (with -Wextra) about casts between pointers to different
function types. The type 'void(*)(void)' works as a 'void*' for function
pointers, cleaning the warning.

0ddc0f47bd Several details about 5.4.0 rc1
Corrected several small details: added 'const', adjusts in tabs x
spaces, removed unused #includes and #defines, misspellings, etc.

ba9cd0d25a Change in the prefix of messages from searchers
The initial "\n\t" to properly indent a searcher message is being added
by 'findloader' when building the error message, instead of being
included in the original message by each searcher itself.

b96b0b5abb Added macro 'luaL_pushfail'
The macro 'luaL_pushfail' documents all places in the standard libraries
that return nil to signal some kind of failure. It is defined as
'lua_pushnil'. The manual also got a notation (@fail) to document those
returns. The tests were changed to be agnostic regarding whether 'fail'
is 'nil' or 'false'.

3c0d3c6fbe Avoid using addresses of static variables as unique keys
The addresses of static variables may be different for different
instances of Lua, making these instances incompatible if they use
these addresses as unique keys in the registry (or other tables).

b14609032c Avoid the creation of too many strings in 'package'
Both when setting a path and searching for a file ('searchpath'),
this commit reduces the number of intermediate strings created
in Lua.
(For setting a path the change is not relevant, because this is
done only twice when loading the module. Anyway, it is a nice example
of how to use auxlib buffers to manipulate strings in the C API.)

ed2872cd3b 'require' returns where module was found
The function 'require' returns the *loader data* as a second result.
For file searchers, this data is the path where they found the module.

f99509581e Removed extra information from RCS keyword strings

ccf6d098f6 'searchpath' creates less temporary strings
When creating error messages, package loaders may create dozens of
temporary strings (one or more for each tried template). This change
reduces the number of these strings, and avoid creating some of
them if the search is successful.
