Suppose a function private_foo() has a symbol private_foo and also a
another one (an alias) named public_foo. Then suppose we want to
filter out sub-type changes to private_foo(). But then we still want
to see changes to public_foo.
This patch does add this feature. The [suppress_function] directive
now has a new (hidden) boolean 'allow_other_aliases' property. When
set to 'yes' or 'true', if the function being looked at has an alias
symbol that does *NOT* match the other properties of the directive,
then the directive doesn't suppress reports for the function. This
new property is set to yes by default.
This means that when a function has got multiple aliases, to suppress
the function, one needs to write a regular expression that matches the
names of aliases. Otherwise the function will not be suppressed.
* include/abg-comparison.h (function_suppression::{get,
set}_allow_other_aliases): Declare new member functions.
* src/abg-comparison.cc
(function_suppression::priv::allow_other_aliases_): New data
member.

(function_suppression::{get, set}_allow_other_aliases): Define new
member functions.
(read_function_suppression): Parse the new "allow_other_aliases"
property.
(function_suppression::suppresses_function): Update to evaluate
the new 'allow_other_aliases' property when there is a property to
match against some a symbol name of the function.
(corpus_diff::report): Fix the printing of function aliases when
printing sub-type changes to properly emit the plural of the word
'symbol' when the function has several aliases.

new member function.
