Don't get stuck on cyclic graphs where one edge has multiple outputs.

Fixes #934. Plan::AddSubTarget() tracks in want_ if each edge has been
visited and visits every edge only once.  But Plan::CheckDependencyCycle()
worked on nodes however, so if a cycle was entered through an edge with
multiple outputs, ninja would fail to detect that cycle.

Move cycle detection to look for duplicate edges instead of nodes to fix
this.  The extra jump makes CheckDependencyCycle() a bit slower: for a
synthetic build file with 10000 serial build steps, `ninja -n` now takes
0.32s instead of 0.26s before on my laptop.  In practice, projects have
a dependency change length on the order of 50, so there shouldn't be a
noticeable slowdown in practice.  (If this does end up being a problem:
CheckDependencyCycle() currently does O(n) work and is called O(m) times
from AddSubTarget(), so I think cycle checking is O(n^2) in the build
depth.  So instead of worrying about constant overhead, we could use
a set<> instead of a stack<>.  But it doesn't seem to be a problem in
practice.)

Move warning emission on dupe edges from State to ManifestParser.

This will make it easier to optionally make this an error (because
ManifestParser has a way of printing errors), and it'll also make
it easier to make the tests quiet again.

Don't crash on cyclic references between rule bindings.

Fixes #902.

This dynamically detects cycles.  I like this approach less than
detecting them statically when parsing rules [1], but it has the
advantage that it doesn't break existing ninja manifest files.

It has the disadvantage that it slows down manifest_parser_perftest by
3.9%.

Another crash fix for duplicate edges. Fixes #939.

Patch #933 fixed a crash with duplicate edges by not adding edges to the
graph if all the edge's outputs are already built by other edges.
However, it added the edge to the out_edges of the edge's input nodes
before deleting it, letting inputs refer to dead edges.

To fix, move the check for deleting an edge above the code that adds
inputs.  Expand VerifyGraph() to check that nodes don't refer to edges
that aren't present in the state.

Make failing stat() calls abort the build.

Make failing stat() calls abort the build.

Fixes #830, fixes #904.

In practice, this either happens with 64-bit inodes and a 32-bit
userspace when building without -D_FILE_OFFSET_BITS=64 in CFLAGS, or
when a filename is longer than the system file length limit.

Since DiskInterface::Stat() returns -1 on error, and Node used -1 on
"stat state unknown", not aborting the build lead to ninja stat()ing the
same file over and over again, until it finally ran out of stack. That's
now fixed.

* Change RecomputeOutputsDirty() to return success instead of dirty
  state (like RecomputeDirty()) and return the dirty state in a bool
  outparam
* Node::Stat()s old return value wasn't used anywhere, change the
  function to return success instead and add an |err| outparam
* Node::StatIfNecessary()'s old return value was used only in one place.
  Change that place to explicitly check status_known() and make
  StatIfNecessary() return success and add an |err| outparam
* Plan::CleanNode() can now fail, make it return bool and add an |err|
  outparam
