The previous implementation of buffered_reader always reads from the
unbuffered reader into the internal buffer, and then dumps the data onto
the destination. This is inefficient, as sometimes it's possible to read
directly into the destination. The previous strategy generates more
memory copies and unbuffered reads than necessary.
Follow up to #19079, which made test names fully qualified.
This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit:
"priority_queue.test.std.PriorityQueue: shrinkAndFree"
and the same test's name after the changes in this commit:
"priority_queue.test.shrinkAndFree"
This allows setting a custom buffer size. In this case I wanted it
because using a buffer size large enough to fit a TLS ciphertext record
elides a memcpy().
This commit also adds `readAtLeast` to the Reader interface.

LinearFifo is removed from BufferedWriter
Basically, LinearFifo does extra work via copying bytes and increasing
an offset.
We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
