This CL removes the Loop base class as it adds no functionality. Other
base classes have had their ToJavaScript methods set as pure virtual and
their constructors made protected.

This CL cleans up some of the JS generation code to make it easier to

This CL inlines the FormCalc method names instead of using a lookup
array. Many of the names were only referenced once and this makes the
code a lot simpler to read.

This CL merges the ToJavaScript and the ToImpliedJS methods in the
FormCalc expressions. The type of return is passed as a paramter to
ToJavaScript.

This CL makes the use of CXFA_IsTooBig consistent and universal across
all of the ToJavascript and related methods. Previously this method
was only applied in some calls. It is now being tested as a
precondition and postcondition on every call and as a post condition
for the entire translation process.
There are some size checks within methods that potentially generate
large amounts of JS that have been left in.

There exists a similar check for the parser, but it doesn't catch all
cases of excessive memory usage, since a single parse step can
generate multiple expressions that need to be converted or other cases
where the parse depth doesn't match the emission depth later.
Due to the expressions appearing in two different inheritence
hierachies the depth information needs to be stored outside of the
classes, thus the new depth class.
Another way to handle this would be to change the method calls to take
in a visitor object that tracks depth. This would require significant
reworking of some of the code, so I am going to file a bug about doing
that conversion as a cleanup.

Automated using git grep & sed.
Replace StringC classes with StringView classes.
Remove the CFX_ prefix and put string classes in fxcrt namespace.
Change AsStringC() to AsStringView().
Rename tests from TEST(fxcrt, *String*Foo) to TEST(*String*,
Foo).
Couple of tests needed to have their names regularlized.

This method duplicates the behaviour of the const [] operator and
doesn't offer any additional safety. Folding them into one
implementation.
SetAt is retained, since implementing the non-const [] operator to
replace SetAt has potential performance concerns. Specifically many
non-obvious cases of reading an element using [] will cause a realloc
& copy.

The various string/byte classes support Mid(), Left(), and Right() for
extracting substrings. Mid() can handle all possible cases, but Left()
and Right() are useful for common cases and more explicit about what
is going on.
Calls like Mid(offset, length - offset) can be converted to
Right(length - offset). Calls like Mid(0, length) can be converted to
Left(length).
If the substring being extracted does not extend all the way to one of
the edges of the string, then Mid() still needs to be used.

This support is being removed from CFX_ByteString, CFX_ByteStringC,
CFX_WideString, and CFX_WideStringC. This standardizes all of these
classes to only have one Mid method that takes in 2 params, offset and
count. Count now must be positive. The old behaviour of calculating
the length for the user if -1 is passed in for the count has been
removed. This work is in preperation for converting these classes to
not accept negative lengths anywhere and thus make the underlying size
type unsigned.
