    Declare many structures const (closes #3552) · 05df9d08

    Many structs used in mutt are actually constant but are defined
    without the 'const' keyword. This can slow initialization (slightly)
    in some environments due to extra copying and increases the amount of
    writable RAM required at run-time, which can be significant on non-MMU
    systems. Using const can also increase the opportunities for compiler
    optimization.
    
    The attached patch marks many such structures as const. On my test x86
    build, this reduces the size of .data by over 50%.
