We've decided to leave logging to third-parties (there are too
many formats), which others have done.

And we can't change the behavior of the various response
fields at this point anyway. Plus I argue they're correct and
match their documention.

The compilers used to generate only one 'm' symbol
to record the stack frame size for each function.

In cmd/nm, the 'm' and 'f' symbols are handled in
the same switch case with a special exception for
the symbol described above called ".frame".

Now that the compilers emit additional 'm' symbols
for precise garbage collection of the stack, the
current logic is incorrect. cmd/nm will attempt to
interpret these new 'm' symbols as 'f' symbols and
add them to the file name index table.

This fails with an out-of-memory condition when
zenter encounters an 'm' symbol with a very large
value (usually the .args symbol indicating a
variadic NOSPLIT function).

Race detector runtime expects values passed to MapShadow() to be page-aligned,
because they are used in mmap() call. If they are not aligned mmap() trims

The smtp package originally allowed PLAIN whenever, but then
the TLS check was added for paranoia, but it's too paranoid:
it prevents using PLAIN auth even from localhost to localhost
when the server advertises PLAIN support.

This CL also permits the client to send PLAIN if the server
advertises it.

Save an allocation per GET request and don't call io.LimitedReader(r, 0)
just to read 0 bytes.  There's already an eofReader global variable
for when we just want a non-nil io.Reader to immediately EOF.
