[Bug-readline] [PATCH] Improve alignment in some structures to save memory space

[Дилян Палаузов]

Reorder some fields, so that the compiler does not insert padding bits, in
order to align the data.  In turn, less memory is needed to store the
structures.

The reordering is based on running the compiler with -Wpadded on 64bit system.
