Drop UniValue::getBool method because it is easy to confuse with the
UniValue::get_bool method, and could potentially cause bugs. Unlike get_bool,
getBool doesn't ensure that the value is a boolean and returns false for all
integer, string, array, and object values instead of throwing an exceptions.
The getBool method is also redundant because it is an alias for isTrue. There
were only 5 getBool() calls in the codebase, so this commit replaces them with
isTrue() or get_bool() calls as appropriate.
These changes were originally made by MarcoFalke in
https://github.com/bitcoin/bitcoin/pull/26213 but were dropped to limit the
scope of that PR.

Pull request description:
This shouldn't matter too much, unless a really large string is pushed into a json struct, but I think it also clarifies the code.

By throwing a custom exception from `Univalue::checkType` (instead of a plain
std::runtime_error) and catching it on the RPC server request handler.
So we properly return RPC_TYPE_ERROR (-3) on arg type errors and
not the general RPC_MISC_ERROR (-1).
fa23c19750 univalue: Avoid narrowing and verbose int constructors (MacroFake)
fa3a9a1e8d rpc: Select int-UniValue constructor for enum value in upgradewallet RPC (MacroFake)
Pull request description:
As UniValue provides several constructors for integral types, the
compiler is unable to select one if the passed type does not exactly
match. This is unintuitive for developers and forces them to write
verbose and brittle code. (Refer to `-Wnarrowing` compiler warning)
For example, there are many places where an unsigned int is cast to a
signed int. While the cast is safe in practice, it is still needlessly
verbose and confusing as the value can never be negative. In fact it
might even be unsafe if the unsigned value is large enough to map to a
negative signed one.
Fix this issue and other (minor) type issues.

Mostly changes to remove src/univalue exceptions from the various linters,
and the required code changes to make them happy. As well as minor doc
changes.
Fix https://github.com/bitcoin/bitcoin/issues/6558. In particular, stop
parsing JSON after the first object or array is finished. Check that no
other garbage follows, and fail the parser if it does.
JSON makes no distinction between numbers and reals, and our code
doesn't need to do so either.
This removes VREAL, as well as its specific post-processing in
`UniValue::write`. Non-monetary amounts do not need to be forcibly
formatted with 8 decimals, so the extra roundtrip was unnecessary
(and potentially loses precision).
Univalue's parsing of \u escape sequences did not handle NUL characters
correctly. They were, effectively, dropped. The extended test-case
fails with the old code, and is fixed with this patch.
- implement find_value() function for UniValue
- replace all Array/Value/Object types with UniValues, remove JSON Spirit to UniValue wrapper
- remove JSON Spirit sources
