2024-08-26treewide: fix a bunch of lintsJade Lovelace
Fixes: - Identifiers starting with _ are prohibited - Some driveby header dependency cleaning which wound up with doing some extra fixups. - Fucking C style casts, man. C++ made these 1000% worse by letting you also do memory corruption with them with references. - Remove casts to Expr * where ExprBlackHole is an incomplete type by introducing an explicitly-cast eBlackHoleAddr as Expr *. - An incredibly illegal cast of the text bytes of the StorePath hash into a size_t directly. You can't DO THAT. Replaced with actually parsing the hash so we get 100% of the bits being entropy, then memcpying the start of the hash. If this shows up in a profile we should just make the hash parser faster with a lookup table or something sensible like that. - This horrendous bit of UB which I thankfully slapped a deprecation warning on, built, and it didn't trigger anywhere so it was dead code and I just deleted it. But holy crap you *cannot* do that. inline void mkString(const Symbol & s) { mkString(((const std::string &) s).c_str()); } - Some wrong lints. Lots of wrong macro lints, one wrong suspicious-sizeof lint triggered by the template being instantiated with only pointers, but the calculation being correct for both pointers and not-pointers. - Exceptions in destructors strike again. I tried to catch the exceptions that might actually happen rather than all the exceptions imaginable. We can let the runtime hard-kill it on other exceptions imo.

2024-07-20libexpr: add a strongly typed version of gcAllocBytes()Qyriad
This commit adds a new helper template function to gc-alloc.hh (which is probably where you want to look at first, O great reviewer [custom file ordering in review diffs when]), which uses a type argument to determine the size to allocate, rather than making the caller use sizeof().

2024-07-20libexpr: rename confusing makeImmutableString -> gcCopyStringIfNeededQyriad
The purpose of this function has little to do with immutability. Value's strings are never mutated, and the point of this function is to singleton empty strings. Change-Id: Ifd41dd952409d54e4d3de9ab59064e6928b0e480
