* Remove duplicate namespace aliases so they don't produce syntax errors.
DACA2 results showed new SymbolDatabase syntax errors when duplicate
namespace aliases were simplified improperly. The solution is to remove
them in the tokenizer when found.
* Add tests for deleting namespace aliases at end of token list.
* Use eraseTokens to delete multiple tokens at once.
* Optimised simplifyKnownVariables
Changed the check for references to constant variables so instead of iterating through all tokens looking for references (which is very slow for large files), usages of each known variable are recorded so each usage can be checked for whether or not it is a reference. Just checking known usages is a lot quicker than checking through all tokens.
* Fixed test error caused by incorrect code
* Fixes to constant variable simplification optimisation
Indexing variables by varId is easier than by Token pointer, but means we also have to store a reference to the constant variable Token in another collection.
Switched to using unordered_map over map as it has slightly better find performance.
* Fixed incorrect simplification behaviour
This should remove constant variables correctly and efficiently. Requires additional functions, Token::deleteThisInPlace() and TokenList::front(Token*).
* Added setter for TokenList::first
This allows code that adds and removes Tokens from the list to do so without copying nodes into other nodes, which sometimes create difficulties.
* Added deleteThisInPlace function
This allows a token to delete itself without invalidating pointers to the node after it. If this token is the first or last in a list the calling code will have to remember to change the list's front or back.
* Added declaration for deleteThisInPlace()
* Removed premature MatchCompiler optimisation
* Added and removed some functions
Added declaration for deleteToken(Token*) which deletes a single token from the list
Removed public front(Token*) because it broke encapsulation
* Implemented deleteToken(Token*) function
* Removed 'delete this' from deleteThisInPlace
* Switched to using safer function
TokenList::deleteToken is better than calling straight into Token::deleteThisInPlace because it doesn't call delete this and doesn't break the TokenList's encapsulation.
* Replace constant variables in reverse order
This fixes the problem where you have two constant value assignment statements in a row. Replacing and deleting them in reverse order means we avoid the problem of deleteThis() potentially invalidating the pointer to the start of the next assignment statement
* Removed unneeded and unsafe deleteThisInPlace
* Removed unneeded and unsafe deleteThisInPlace
* Removed unneeded deleteToken
* Removed unneeded deleteToken
* Removed extra whitespace
* Don't remove the volatile keyword so we can properly overload functions.
I fixed all the checks that had tests that use volatile. There will
probably be more changes needed due to lack of test coverage for
volatile in some checks.
* Fix unused private function warning.
* Add support for namespace aliases and C++17 nested namespaces.
These are implemented as tokenizer simplifications so changes are not
needed to the tokenizer and symbol database.
* Fix codacy warning.
* SymbolDatabase: harden code for missing links
Missing links for templates are common so check links before using them
to prevent crashes.
* SymbolDatabase: replace link check and single token match with match of two tokens
On Windows searching for the last colon finds the colon which is part of
the path of the source file (e.g. "C:/projects/a.cpp"). Thus the path is
saved incomplete. This fix searches for the second instead of the last
colon and uses the data after the second colon as the path of the source
file.
* SymbolDatabase: improve checking of uninstantiated templates
* Add bailout and debug warning for '>' token without a link in SymbolDatabase::findFunction()..
Don't crash on bad code simplification from tokenizer.
Three attributes are reset in this member function even if their values
are stored in the same token object.
Move a corresponding sanity check so that less assignments could be
performed eventually.

This hopefully fixes all Travis crashes when running cppcheck:
[./test/Analysis/stack-addr-ps.c] (error) Internal error: Child process crashed with signal 11 [cppcheckError]
[./test/Index/complete-pointer-and-reference-to-functions.cpp] (error) Internal error: Child process crashed with signal 11 [cppcheckError]
[./test/SemaCXX/vararg-non-pod.cpp] (error) Internal error: Child process crashed with signal 11 [cppcheckError]
* Added parsing suppressions from dump xml.
* Added code to dump suppressions to an xml file
* Added declaration for dump function
* Suppressions will now be written to the xml file when a dump is requested
* Fixed syntax error
* Removed excess whitespace
* Fixed indentation to be consistent
* Fixed indentation to be consistent
* Fixed indentation to be consistent
* Added missing include for ErrorLogger::toXml
* Fixed suggestions from pull request #1166
Switched to using ranged for loop to iterate through suppressions.
Made the line number attribute optional, rather than 0 if not specified. This means when Python deserialises it it will be None, which is more pythonic.
* Implemented checking suppressions in reportError
This modification expects suppressions and a function to be called to write a line of output to be passed in. The function checks if any of the suppressions match the warning (with the new Suppression.isMatch function) and if so returns None. This change maintains the old behaviour of returning the warning text, but adds the possibility of returning None if the warning was suppressed.
* Fixed code quality warnings
* Removed more extraneous whitespace
In 9cea2d6df, simplifications were removed for a number of functions
which should instead be handled with configurations. The commit did
however not update the description of the function, do this now.
Also sin() and sinh() and their float and long double versions were
missing from the comment so add these as well.
* Check for double frees when using smart pointers
* Some updates from feedback
* Add test for mismatch allocation
* Constants
* Check smart pointer deleter
* Switch order
* Use next
* Add owned state
* Fix handling of leaks
* Use ast for checking addressof operator
* Remove stray character
* Add a test for mismatch allocator
* Add another test for deallocating with custom function
