feat: Add support for symbolic links
All the pieces were in place, we just needed to put them together.

Sorry, but sub-500 LoC isn't gonna work anymore...

fix: Use memcpy() in minitar_strlcpy()
This allows the platform to provide a more optimized and FAST version of memcpy than
our manual implementation inside strlcpy.

Shouldn't have rushed to 1.0.0 so quickly. Oh well, I guess I can allow 1.1.0...

d123c49946 Do not automatically read an entry's contents, leave it up to the user
This API change modifies minitar_read_entry to skip over the file's contents and instead store the current read position in the entry.

struct minitar_entry no longer has a ptr field, but has a position field (of type fpos_t) for internal use.

minitar_free_entry no longer frees entry->ptr.

A new function has been added, minitar_read_contents().
It reads a certain number of bytes from an entry (which is capped to the entry's size) into a user-provided buffer.
This function can be called at any time provided it is called with a valid archive stream and entry.
This is achieved by calling fgetpos() to store the start of the entry's contents in the entry's position field while reading it.
Then minitar_read_contents() will store the current position, rewind to the entry's position, read the chosen number of bytes from the archive, and then rewind back to the current position.

Since this is a breaking change, it needs a major version bump. Since there was no version, I bumped it to 1.0.0 :)
