There has been a regression such that ./t0030-mount.sh fails on
'ipfs mount' fails when there is no mount dir
The issue was a change in how fuse errors are reported to the client
process. We have introduced an optimistic categorization that hides
the obscure fusermount error and replaces it with something a bit
more helpful.

Except when there is an explicit os.Exit(1) after the Critical line,
then replace with Fatal{,f}.
golang's log and logrus already call os.Exit(1) by default with Fatal.

This configuration is supported since GoBuilder 1.16.0 so now we should be able to build windows binaries in GoBuilder

Folks operating at the Unix-filesystem level shouldn't care about that
level of Merkle-DAG detail. Before this commit we had:
$ ipfs unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox:
... several lines of empty-string names ...
And with this commit we have:
$ ipfs unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
I also reworked the argument-prefixing (object.Argument) in the output
marshaller to avoid redundancies like:
$ ipfs unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox:
/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox
As a side-effect of this rework, we no longer have the trailing blank
line that we used to have after the final directory listing.
The new ErrImplementation is like Python's NotImplementedError, and is
mostly a way to guard against external changes that would need
associated updates in this code. For example, once we see something
that's neither a file nor a directory, we'll have to update the switch
statement to handle those objects.

This is similar to 'ipfs ls ...', but it:
* Lists file sizes that match the content size:
$ ipfs --encoding=json unixfs ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4
{
"Objects": [
{
"Argument": "/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4",
"Links": [
{
"Name": "busybox",
"Hash": "QmPbjmmci73roXf9VijpyQGgRJZthiQfnEetaMRGoGYV5a",
"Size": 1947624,
"Type": 2
}
]
}
]
}
$ ipfs cat /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4/busybox | wc -c
1947624
'ipfs ls ...', on the other hand, is using the Merkle-descendant
size, which also includes fanout links and the typing information
unixfs objects store in their Data:
$ ipfs --encoding=json ls /ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4
{
"Objects": [
{
"Hash": "/ipfs/QmSRCHG21Sbqm3EJG9aEBo4vS7Fqu86pAjqf99MyCdNxZ4",
"Links": [
{
"Name": "busybox",
"Hash": "QmPbjmmci73roXf9VijpyQGgRJZthiQfnEetaMRGoGYV5a",
"Size": 1948128,
"Type": 2
}
]
}
]
}
* Has a simpler text output corresponding to POSIX ls [1]:
$ ipfs unixfs ls /ipfs/QmV2FrBtvue5ve7vxbAzKz3mTdWq8wfMNPwYd8d9KHksCF/gentoo/stage3/amd64/2015-04-02

The minimal output allows us to start off with POSIX compliance and
then add options (which may or may not be POSIX compatible) to
adjust the output format as we get a better feel for what we need
([2] through [3]).

Since 607468a9 (beautify 'ipfs ls' and 'ipfs object links', #833)
we've had these. That pull request was about text/tabwriter [1] and
elastic tabstops [2], but we don't need a column separator at the end
of each line.

Different mutliaddrs is not enough. Nodes may share transports.
NAT port mappings will likely only work on the base IP/TCP port
pair. We go one step further, and require different root (IP)
addrs. Just in case some NATs group by IP. In practice, this is
what we want: use addresses only if hosts that are on different
parts of the network have seen this address.
If the same peer observed the same address twice, it would be
double counted as different observations. This change adds a map
to make sure we're counting each observer once.
This is easily extended to require more than two observations,
but i have not yet encountered NATs for whom this is relevant.
