dc6985f9d2 Avoid bogus -Wmaybe-uninitialized from gcc 11 
It doesn't really matter that number_buf is not initialized because its
first characters are not going to be used anyhow (png_format_number()
returns a pointer to the actually used part of the string at the end),
but gcc-11 warns about it, so do initialize it just to make it happy.

9c0d5c77bf Call png_image_free_function without guarding it with png_safe_execute 
png_image_free_function (or any other destructor) should never fail.
Destructors need not and must not be executed under png_safe_execute.

Reference: CVE-2019-7317, use-after-free in png_image_free

ceb327789b Remove top-level const from function-scope variables 
As per the const correctness rules, top-level const-ness of data
in automatic scopes does not propagate outside of these scopes
(unlike const-ness at lower levels, such as pointers to const data).

Previously, const was used liberally, but inconsistently across the
libpng codebase. Using const wherever applicable is not incorrect.
However, _consistent_ use of const is difficult to maintain in such
conditions.

In conclusion, we shall continue to use const only where doing so is
strictly necessary:

1. If a function guarantees that it will not modify an argument
   passed by pointer, the corresponding function parameter should be
   a pointer-to-const (const T *).

2. Static data should not be modified, therefore it should be const.

1ef8882814 Replace the remaining uses of PNG_CONST with const 
In v1.6.0, compiler support for const became a requirement.
It should be used consistently. To maintain backwards compatibility,
PNG_CONST is still maintained in deprecated form.
