On ELF systems, we could use the GOT for those

Enabling the fulltext index will use significantly more memory as
the text of all source code, the respective suffixarray, and the
file set data structure is kept in memory. At the moment there is
about 6Mb of source code (~1400 files) indexed under GOROOT.
Source code + suffix array together consume 5*(size of source) or
about 30Mb. The file set data structure consumes about 4b/src line.

The presentation of the results needs tuning. In particular,

- The new version of godoc consumes about the same space after indexing
has completed, but indexing is half the speed. Significant space savings
are expected from smaller ASTs, but since they are thrown away after a
file has been indexed, this is not visible anymore. The slower indexing
time is due to the much more expensive computation of line information.
However, with the new compressed position information, indexing can be
rewritten and simplified. Furthermore, computing the line info can be
done more efficiently.
New godoc, immediately after indexing completed (best of three runs):
PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZE

Old godoc, immediately after indexing completed (best of three runs):

2010/12/03 14:51:32 index updated (24.892s, 18765 unique words, 393830 spots)
2010/12/03 14:51:32 bytes=66404528 footprint=163907832
2010/12/03 14:51:32 bytes=46282224 footprint=163907832
The different numbers for unique words/spots stem from the fact the the
two workspaces are not exactly identical. The new godoc maintains a large
file set data structure during indexing which (probably) is the reason
for the larger heap (90858456 vs 66404528) before garbage collection.

Previously we checked the certificate chain from the leaf
upwards and expected to jump from the last cert in the chain to
a root certificate.
Although technically correct, there are a number of sites with
problems including out-of-order certs, superfluous certs and
missing certs.
The last of these requires AIA chasing, which is a lot of
complexity. However, we can address the more common cases by
using a pool building algorithm, as browsers do.
We build a pool of root certificates and a pool from the
server's chain. We then try to build a path to a root
certificate, using either of these pools.
This differs from the behaviour of, say, Firefox in that Firefox
will accumulate intermedite certificate in a persistent pool in
the hope that it can use them to fill in gaps in future chains.
We don't do that because it leads to confusing errors which only
occur based on the order to sites visited.
This change also enabled SNI for tls.Dial so that sites will return
the correct certificate chain.

1) Be sure to use the eval-time encoder/decoder rather than
the compile-time decoder. In a few cases the receiver for
the compiling encoder was being pickled incorrectly into a
closure.
(This is the fix for issue 1238).
2) Get the innermost name right when given a pointer to an
unnamed type.
3) Use a count to delineate interface values, making it
possible to ignore values without having a concrete type
to encode into. This is a protocol change but only for the
new feature, so it shouldn't affect anyone. The old test
worked because, amazingly, it depended on bug #1.
Fixes#1238.
