[PATCH][GSoc] Changed signed flags to unsigned type

[Vedant Bassi <sharababy.dev@xxxxxxxxx>]

As part of my microproject :

Use unsigned integral type for collection of bits:
Pick one field of a structure that (1) is of signed integral type and
(2) is used as a collection of multiple bits. Discuss if there is a
good reason why it has to be a signed integral field and change it to
an unsigned type otherwise.

I have found several structures where a signed int was used on flags
for bitwise & to check various cases.

-------

result : the changes were made in bisect.h , parse-options.h and  builtin/add.c

I have not yet  tested these changes.
