Follows 34b1920e7b.
JSON functions and ToString are movec to their own headers.
Also clean out a few PersistentRooted usage to use the 2-phase init to
clean up scriptInterface usage.
With these functions split off, we can finally clean out headers and
remove ScriptInterface.h from most of them, in favour of smaller and
more precise headers.
Take the opportunity to clarify some comments regarding Mutability.

This was SVN commit r25434.
All ToJSVal/FromJSVal definitions are put in a separate header.
Remove AssignOr[To/From]JSVal duplication.
The functions were already static so this is rather straightforward.

- Check for pending exceptions after function calls and script
executions.
- Call LOGERROR instead of JS_ReportError when there is a conversion
error in FromJSVal, since that can only be called from C++ (where JS
errors don't really make sense). Instead, C++ callers of FromJSVal
should handle the failure and, themselves, either report an error or
simply do something else.
- Wrap JS_ReportError since that makes updating it later easier.
This isn't a systematical fix since ToJSVal also ought return a boolean
for failures, and we probably should trigger errors instead of warnings
on 'implicit' conversions, rather a preparation diff.

This was SVN commit r24187.
JSAutoRequest is required before calling into most JSAPI methods, for GC
reasons.
Calling it is required and fragile as one must not forget.
Further, SM52 and later make manipulating JSContext* dangerous as that
can cross Compartment(Realm in SM68) barriers (and ScriptInterface now
matches a Compartment).
The solution to both problems is to avoid using JSContext* in 0 A.D.
itself. To achieve this, a Request class is introduced, and must be used
to access a JSContext* from a scriptInterface. Further, Request is
passed to other ScriptInterface functions isntead of JSContext*, making
it obvious that the caller has already called it, reducing errors and
redundant JSAutoRequest calls.
Only JSNative functions now get a naked JSContext* without protection,
but the likelihood of forgetting a request is lower since many
ScriptInterface functions now expect it.
JSContext* is directly passed to JSAPI functions only.

This was SVN commit r24176.
The commit introduced support for arbitrary lobby CreateGUIMessage
JS::Value arguments but didn't transfer wstring_from_utf8 appropriately.
Instead of enlengthening the code by reintroducing utf8_from_wstring
everyhwere, shorten the code and specialize ToJSVal for
glooxwrapper::string and gloox enums.
Avoid string copies for XmppClient getters, refs D1668:
Change GetPresence() and GetRole() to return the pointer to the string
literal instead of copy constructing a std::string each call.
Don't reintroduce the unneeded utf8_from_wstring conversions for the
untranslatable ASCII identifiers returned by GetPresence() and
GetRole().
Change GetSubject() to return a const ref to the member instead of copy
assigning the std::string to an output value.
Change m_Subject to std::wstring to avoid constructing a copy using
wstring_from_utf8 each GetSubject() call.
Change gloox enum to translatable string functions to be static, so as
to use them in the new ToJSVal functions (enabled by not calling
CertificateErrorToString from ConnectionErrorToString anyymore in
92fc34c87c/D2274).
Avoid per-player string copies in m_PlayerMap:
Change m_PlayerMap value type from std::vector<std::string> to a new
PlayerMap struct with named members for readability.
Use gloox enums as PlayerMap values to avoid constructing (performance)
and storing (memory footprint) std::strings.
The JS String is created from the pointer to the ASCII string literal
without intermediaries.
Use glooxwrapper::string for nickname and m_Rating since it's the data
source type received in relevant places, but that might be improved for
performance with std::wstring.
Construct map values in place where possible and post error instead of
silently inserting if an existing value is to be modified.
Avoid repeated std::map lookups on string keys by caching the
PlayerMap::iterator where available.
Remove some glooxwrapper::string to_string() calls redundant with its
operator<< and improve DbgXMPP gloox enum output.
Transfer rating too upon nickchange.
