ef48dfa310 exp/locale/collate: added indices to builder for reusing blocks between locales.
Refactored build + buildTrie into build + buildOrdering.
Note that since the tailoring code is not checked in yet, all tailorings are identical
to root.  The table therefore should not and does not grow at this point.

5a78e5ea4c exp/locale/collate: Added functionality to parse and process LDML files
for both locale-specific exemplar characters and tailorings to
the collation table.
Some specifices:
- Moved stringSet to the beginning of the file and added some functionality
  to parse command line files.
- openReader now modifies the input URL for localFiles to guarantee that
  any http source listed in the generated file is indeed this source.
- Note that the implementation of the Tailoring API used by maketables.go
  is not yet checked in. So for now adding tailorings are simply no-ops.
- The generated file of exemplar characters will be used somewhere else.
  Here is a snippet of how the body of the generated file looks like:

type exemplarType int
const (
        exCharacters exemplarType = iota
        exContractions
        exPunctuation
        exAuxiliary
        exCurrency
        exIndex
        exN
)

var exemplarCharacters = map[string][exN]string{
        "af": [exN]string{
                0: "a á â b c d e é è ê ë f g h i î ï j k l m n o ô ö p q r s t u û v w x y z",
                3: "á à â ä ã æ ç é è ê ë í ì î ï ó ò ô ö ú ù û ü ý",
                4: "a b c d e f g h i j k l m n o p q r s t u v w x y z",
        },

18aa55c169 exp/locale/collate: first changes that introduce implementation of tailorings:
- Elements in the array are now sorted as a linked list.  This makes it easier to
  apply tailorings.
- Added code to sort entries by collation elements.
- Added logical reset points.  This is used for tailoring relative to certain
  properties, rather than characters.

NOTE: all code for type entry should now be in order.go.  To keep the diffs for
this CL reasonable, though, the existing code is left in builder.go.  I'll move
this in a separate CL.

c61a185f35 exp/locale/collate: add code to ignore tests with (unpaired) surrogates.
In the regtest data, surrogates are assigned primary weights based on
the surrogate code point value.  Go now converts surrogates to FFFD, however,
meaning that the primary weight is based on this code point instead.
This change drops tests with surrogates and lets the tests pass.

a8357f0160 exp/locale/collate/build: fixed bug that was exposed by experimenting
with table changes.
NOTE: there is no test for this, but 1) the code has now the same
control flow as scan in exp/locale/collate/contract.go, which is
tested and 2) Builder verifies the generated table so bugs in this
code are quickly and easily found (which is how this bug was discovered).

98883c811a exp/locale/collate: let regtest generate its own collation table.
The main table will need to get a slightly different collation table as the one
used by regtest, as the regtest is based on the standard UCA DUCET, while
the locale-specific tables are all based on a CLDR root table.
This change allows changing the table without affecting the regression test.

27cb1cbb2e exp/html: skip render and reparse on more tests that build badly-formed parse trees
All of the remaining tests that had as status of PARSE rather than PASS had
good reasons for not passing the render-and-reparse step: the correct parse tree is
badly formed, so when it is rendered out as HTML, the result doesn't parse into the
same tree. So add them to the list of tests where that step is skipped.

Also, I discovered that it is possible to end up with HTML elements (not just text)
inside a raw text element through reparenting. So change the rendering routines to
handle that situation as sensibly as possible (which still isn't very sensible, but
this is HTML5).

a108369c83 syscall: return EINVAL when string arguments have NUL characters
Since NUL usually terminates strings in underlying syscalls, allowing
it when converting string arguments is a security risk, especially
when dealing with filenames. For example, a program might reason that
filename like "/root/..\x00/" is a subdirectory or "/root/" and allow
access to it, while underlying syscall will treat "\x00" as an end of
that string and the actual filename will be "/root/..", which might
be unexpected. Returning EINVAL when string arguments have NUL in
them makes sure this attack vector is unusable.

89d40b911c exp/locale/collate: changed API of Builder to be more convenient
for dealing with CLDR files:
- Add now taxes a list of indexes of colelems that are variables. Checking and
  handling is now done by the Builder.  VariableTop is now also properly generated
  using the Build method.
- Introduced separate Builder, called Tailoring, for creating tailorings of root
  table.  This clearly separates the functionality for building a table based on
  weights (the allkeys* files) versus tables based on LDML XML files.
- Tailorings are now added by two calls instead of one: SetAnchor and Insert.
  This more closely reflects the structure of LDML side and simplifies the
  implementation of both the client and library side.  It also preserves
  some information that is otherwise hard to recover for the Builder.
- Allow the LDML XML element extend to be passed to Insert.  This simplifies
  both client and library implementation.

cd21eff705 exp/html: make the tokenizer return atoms for tag tokens.
This is part 1 of a 2 part changelist. Part 2 contains the mechanical
change to parse.go to compare atoms (ints) instead of strings.

The overall effect of the two changes are:

10838165d8 exp/locale/collate: fixed two bugs uncovered by regression tests.
The first bug was that tertiary ignorables had the same colElem as
implicit colElems, yielding unexpected results. The current encoding
ensures that a non-implicit colElem is never 0.  This fix uncovered
another bug of the trie that indexed incorrectly into the null block.
This was caused by an unfinished optimization that would avoid the
need to max out the most-significant bits of continuation bytes.
This bug was also present in the trie used in exp/norm and has been
fixed there as well. The appearence of the bug was rare, as the lower
blocks happened to be nearly nil.
