This adds support for compressed ELF sections. This compression is
treated as a framing issue and hence the package APIs all
transparently decompress compressed sections. This requires some
subtlety for (*Section).Open, which returns an io.ReadSeeker: since
the decompressed data comes from an io.Reader, this commit introduces
a Reader-to-ReadSeeker adapter that is efficient for common uses of
Seek and does what it can otherwise.

Fixes #11773.

GCC and LLVM support zlib-compressing DWARF debug sections (and
there's some evidence that this may be happening by default in some
circumstances now).

Add support for reading compressed DWARF sections. Since ELF
relocations apply to the decompressed data, decompression is done
before applying relocations. Since relcations are applied by
debug/elf, decompression must also be handled there.

Note that this is different from compressed ELF sections, which is a
more general mechanism used by very recent versions of GCC.

Updates #11773.

stackBarrier on amd64 sanity checks that it's unwinding the correct
entry in the stack barrier array. However, this check is wrong in two
ways that make it unlikely to catch anything, right or wrong:

1) It checks that savedLRPtr == SP, but, in fact, it should be that
   savedLRPtr+8 == SP because the RET that returned to stackBarrier
   popped the saved LR. However, we didn't notice this check was wrong
   because,

2) the sense of the conditional branch is also wrong.

Fix both of these.

runtime.stackBarrier is a strange function: it is only ever "called" by
smashing its address into a LR slot on the stack. Calling it like this
certainly does not adhere to the rule that r12 is set to the global entry point
before calling it and the prologue instrutions that compute r2 from r12 in fact
just corrupt r2, which is bad because the function that stackBarrier returns to
probably uses r2 to access global data.

Fortunately stackBarrier itself does not access any global data and so does not
depend on the value of r2, meaning we can ignore the ABI rules and simply skip
inserting the prologue instructions into this specific function.

Address.String() used mime.QEncoding to encode the name.

However certain characters are forbidden when an encoded-word is
in a phrase context (see RFC 2047 section 5.3) and these
characters are not encoded by mime.QEncoding.

In this case we now use mime.BEncoding (base64 encoding) so that

Motivation for change:
* Recursive logic is hard to follow, since it tends to apply
things in reverse. On the other hand, the tar formats tend to
describe meta headers as affecting the next entry.
* Recursion also applies changes in the wrong order. Two test
files are attached that use multiple headers. The previous Go
behavior differs from what GNU and BSD tar do.
