Check for JSON error when parsing addon .json files + fixes (#2374)
* cppcheck.cpp: Check for JSON error when parsing addon .json files

This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().

* naming.json: Fix missing comma

* CLI: Fix naming violations detected by addon naming.py via naming.json

* Addon naming: Add argument for validating names of constants

* LIB: Rename functions/variables so they are valid, loosen naming rules

* GUI: Fix naming violations

IOBYTE 3a617fa04a Fix #9472 (Syntax error on valid C++ code) (#2363)
There are probably a lot more valid code patterns that generates syntax
errors so I added "operator" to the error message to make it easier to
find them.

IOBYTE c32a568c1f fix #8965 ("(debug) Executable scope 'x' with unknown function." with rvalue parameter in method) (#2237)
I fixed the AST enough to pass testrunner but I don't believe it is
correct.

This code:

void Foo4(int&&b);

has this AST:

( 'void'
|-Foo4
`-&& 'bool'
  |-int
  `-b 'signed int'

but I don't believe && should have `bool`.

rebnridgway 0d7836f3a0 Calculate token scopes in advance rather than as the tokenlist is iterated (#1882)
* Added scopeinfo member to token class

Moved ScopeInfo2 declaration here as well because that's where it needs to be now.

* Added scopeinfo accessors and declaration to class

* Add new method for calculating scopes

This replaces the methods in the TemplateSimplifier which calculate the current scope as the token list is iterated.  The old method required checking if the scope had changed for every token multiple times (for multiple iterations), which was surprisingly costly.  Calculating scopes in advance like this decreases runtime on a worst-case file by around thirty percent.
ScopeInfo objects are disposed of when the TemplateSimplification is done as they are not used later.

* Add calculateScopes method to header

* Removed code that calculated current scope

This has been replaced by code that calculates the scopes up front and stores them with each token, which is much faster.

* Fixed compile errors from extra parentheses

* Added missing code to fix memory leak

* Added code to actually clean up ScopeInfo structs

* Tidy up a dodgy for loop

* Convert argument to const ref

* Calculate missing scopes

As the templatesimplificator expands templates and does multiple passes it needs to make sure all scopes are calculated.

* Remove copying the scope to the next token

This is now done properly when scopes are calculated.

* Remove call to calculateScopes

This is now done by the TemplateSimplifier.

* Recalculate scopes for every pass of simplifyTemplates

* Add code to calculate extra scopes as they are added

I thought that this might be useful for calculating scopes when Tokens are created, but as there are several ways of creating Tokens that don't guarantee that they are placed in a list it is easier to just calculate scopes when you know you have a list and when you know you're adding to a list.

* Fix several bugs and poorly designed code

Remove the global scopes collection, and clean them up instead by iterating through the tokenlist to find them.  This means scopes can be calculated by functions in the Token class as well as in the Tokenizer class without leaking the scope object.
Fix a couple of bugs in the calculateScopes method and make it more efficient.

* Remove unnecessary calls to calculateScopes

* Move brace to correct position

Calculating scopes during insertToken only needs to happen if we created a new Token.

* Handle 'using namespace' declarations separately

This fixes a bug caused by a statement matching 'struct B < 0 > ;'

* Fix argument name mismatch

* Actually use newScopeInfo when inserting Token

* Switch to using shared_ptr to hold scopeInfos

This means ScopeInfo2 objects get properly cleaned up when they are no longer needed.

* Change ScopeInfo member to be a shared_ptr

* Update code to use shared_ptr

* Add missing include for shared_ptr

* Remove unnecessary cleanup code

This has been replaced by shared_ptr for ScopeInfo2 objects

rikardfalkeborn dc4e7cef88 Run simplifyPlatformTypes on library return types (#1672)
Add a call to simplifyPlatformTypes() in
SymbolDatabase::setValueTypeInTokenList() to simplify return types of
library configured functions. This fixes the FN in #8141. Regression
tests are added, both for the original issue and another FN in the comments.

In order to do that, move simplifyPlatformTypes() to TokenList from Tokenizer.
This is a pure refactoring and does not change any behaviour. The code was
literally copy-pasted from one file to another and in two places
'list.front()' was changed to 'front()'.

When adding the call to simplifyPlatformTypes(), the original type of
v.size() where v is a container is changed from 'size_t' to 'std::size_t'.
Tests are updated accordingly. It can be noted that if v is declared as
'class fred : public std::vector<int> {} v', the original type of 'v.size()'
is still 'size_t' and not 'std::size_t'.

IOBYTE 1faae52d06 Fixed #8960 ("(debug) Unknown type 'x'." with alias in template class alias) (#1643)
* Fixed #8960 ("(debug) Unknown type 'x'." with alias in template class alias)

This commit adds non-template type alias support to the template
simplifier.  Only relatively simple type aliases are supported at this
time. More complex types will be added later.

--debug-warnings will show unsupported type aliases.

Type alias support will be removed from the symbol database in the
future.  Type alias tests have been removed from the symbol database
tests.

* Add the changes.

* Fix codacy warning.

* Fix travis warnings.
