... while retaining all the functionality of stamps.def.
Also fix stamp names encoding only 32 bits of the timestamp, migrate from stamps.def to stamps.json if the latter doesn't exist, delete both on migration to the shared data directory, rescan stamps at startup, and make rescanning a painless process in general by removing invalid entries and adding missing entires at the beginning of the list.
Request ownership is no longer flaky. Requests are now owned by the code that makes requests, and Requests and the RequestManager co-own RequestHandles. RequestManager disowns a RequestHandle if it's done with it or if Request code reports that it's no longer needed.
All libcurl code has been moved to RequestManager. This is nice because once NOHTTP is removed, we can add any number of RequestManager implementations, for example one for Android.
Client outliving RequestManager is still a problem, this will have to be addressed later.
Also Disallow linking against non-C++ system Lua, unless configuring with -Dworkaround_noncpp_lua=true, add -Dworkaround_elusive_bzip2 and friends, and get rid of the -image_base hack for macos.
This is how we'll handle systems where the cert bundle and cert directory is stored where mbedtls doesn't expect it.
Also update tpt-libs to get new curl and mbedtls.
This made it possible to get rid of two GameSave constructors.
Also clean up Client::LoadSaveFile, Client::ReadFile, and Client::WriteFile in the process, and remove unused SaveRenderer::Render
The logging is saved inside the bson data in all online saves, local saves, stamps, and clipboard pieces. It is loaded back when reloading each of those.
See #474 for the format of the data. It is the same format for the bson data. Note that "links" is an array of objects. It can be recursive.
There is some effort to not duplicate information, we don't care if you loaded a stamp 10 times or if you are using the clipboard in your own save. Extra information is mostly not saved for your own stuff, only when you take material from other saves.
Press ctrl+a in debug builds to show what info it is currently saving in Client. Also enabled in snapshots for now.
There is one unrelated change in here, which fixes a crash pointed out by QuanTech. It was also save related and it was too close to the other changes to separate it into another commit. It fixes a crash when saving signs with invalid unicode. the BSON library doesn't like this, it was returning an error but we ignored it, which caused a crash. It now notices those errors. I also had to update several Serialize calls to check if it actually returned save data, or else it then would have started crashing there instead.
Also some debug prints were removed
The crash when opening saves on mac is definitely something to do with the threading, and i'd rather just test this first to see if it fixes it
Copied from my mod almost entirely as-is, with the changes to HTTP.cpp included, also added locks into Download.cpp even though it is probably overkill
cajun is a hard to use library with many necessary features missing. It also has been causing the windows version, and probably the mac version, to randomly crash.
Other json stuff still uses cajun (TODO: remove)
