Store the list of excluded symbols in a sorted list, speeding up
checking for duplicates when inserting new entries.
This is done in the same way as is done for exports and imports
(while the previous implementation was done with a linked list,
based on the implementation for aligncomm).
When linking object files with excluded symbols, there can potentially
be very large numbers of excluded symbols (just like builds with
exports can have a large number of exported symbols).
This improves the link performance somewhat, when linking with large
numbers of excluded symbols.
The later actual use of the excluded symbols within pe-dll.c
handles them via an unordered linked list still, though.

Use a separate explicit max_exports/imports field, instead of
deducing it from the number of allocated elements. Use a named
constant for the incremental growth of the array.
Use bool instead of int for boolean values.
Remove an unnecessary if statement/scope in the def_file_free
function.
Add more verbose comments about parameters, and about insertion
into an array of structs.
Generally use unsigned integers for all array indices and sizes.
The num_exports/imports fields are kept as is as signed integers,
since changing them to unsigned would require a disproportionate
amount of changes ti pe-dll.c to avoid comparisons between signed
and unsigned.
Simply use xrealloc instead of a check and xmalloc/xrealloc;
xrealloc can take NULL as the first parameter (and does a similar
check internally). (This wasn't requested in review though,
but noticed while working on the code.)
