Subword matches for CDT content assist

[markozajc]

Is your feature request related to a problem? Please describe.
While looking for a function, a method, a field, or anything else that CDT's content assist can find, I don't usually start typing from the start of the identifier. For example, when trying to complete object.getValue(), I might start typing object.value. Eclipse CDT does not currently support this.

Describe the solution you'd like
Much like JDT's subword matches feature (enabled in Preferences > Java > Editor > Content Assist), CDT should optionally display matches even if they don't start with the typed in text. This is an example provided on JDT's Tips and Tricks help page:

Describe alternatives you've considered
N/A - I believe it would be wise to implement this similarly to JDT to ensure consistency between languages.
