genv8constants was much slower than necessary due to lack of pipe buffering.

Replace 'Fork me at Github' ribbon with a new one fitting the website's color
scheme.

This allows us to run npm's scripts/relocate.sh script whenever
necessary, if for example node has been 'make install'ed into one
folder, and then you wish to move it into another one.

Link with -Wl,--export-dynamic, makes symbols from the node binary visible to
binary add-ons.

Fixes "undefined symbol: _ZN2v811HandleScopeC1Ev" errors when loading add-ons
on FreeBSD and likely other BSDs.

Fixes #3623.

This reverts commit 928ea564.

Keeping the original Array instance in-place essentially causes a memory leak
on EventEmitters that use an infinite number of event names (an incrementing
counter, for example), which isn't an unreasonable thing to want to do.

Fixes #3702.

* don't assert when fd isn't an open file descriptor

* don't die with a ReferenceError when fd isn't a file descriptor
  you can listen() on

Fixes #3699.

_listen2() emits the error on the next tick. The errno value may have changed
by then.

V8 on ARM requires that armv7 is set. We don't have a good way to detect the
CPU model right now so we pick a default and hope that it works okay for the
majority of people.

Non-scientific sampling - the ARM hardware I have lying around the house -
suggests that ARMv5 and ARMv6 are still most common so armv7=0 it is.

This obviously needs to be revisited sometime in the future.

Compile at -O2 and disable optimizations that trigger gcc bugs.

Some people still reported mksnapshot crashes after commit b40f813b ("build: fix
spurious mksnapshot crashes for good" - so much for that).

Average performance of the -O2 binary is on par with the -O3 binary. Variance
on the http_simple bytes/8 benchmark appears to be slightly greater but small
enough that the possibly of it being noise cannot be excluded.

The new binary very slightly but consistently outperforms the -O3 binary (by
about 0.5%) on the mostly CPU-bound bytes/102400 benchmark. That could be an
artifact of the system I benchmarked it on, a Core 2 Duo with a puny 32 kB of
L1 instruction cache. The smaller binary seems to play nicer with the cache.

A variety of gcc bugs made mksnapshot crash with either a segmentation fault
or a 'pure virtual method callled' run-time error.

After much wailing and gnashing of teeth I managed to deduce that the bugs
show up when:

  1. gcc 4.5.2 for i386-pc-solaris2.11 is used and -fstrict-aliasing is
     enabled, or

  2. gcc version 4.4.6 for x86_64-redhat-linux is used and
     -ffunction-sections -finline-functions at -O2 or higher is enabled

Therefore, disable -ffunction-sections and -fdata-sections unconditionally
and disable -fstrict-aliasing only on Solaris.

The -ffunction-sections and -fdata-sections switches were nonsense anyway
because we don't link with -Wl,--gc-sections.

Before this commit, `fs.unwatchFile(path)` removed *all* listeners for `path`.

The function is overloaded now: `fs.unwatchFile(path)` still removes all
listeners, but `fs.unwatchFile(path, cb)` lets you remove a specific listener.
