lnwire: add new RequiresFeature method
In this commit, we add a new RequiresFeature method to the feature
vector struct. This method allows us to check if the set of features
we're examining *require* that the even portion of a bit pair be set.
This can be used to check if new behavior should be allowed (after we
flip new bits to be required) for existing contexts.

lnwire/feature: remove feature bit number from name
The number and the name will be separate on the rpc level, so we remove
the feature bit from the string. Currently this method is unused apart
from maybe in some rare logging instances.

feature: add new feature pkg to manage feature sets
This commit introduces a feature.Manager, which derives feature vectors
for various contexts within the daemon. The sets can be described via a
staticly compiled format, which makes any runtime adjustments to the
feature sets when the manager is initialized.

lnwire: ensure even/odd features have the same base name
In this commit, we fix a bug in the way we defined our even/odd features
for a particular feature. The check for if a feature bit is part of a
pair assumes that the pair bit has the exact same name as the bit being
queried. The way we defined our feature map didn't take note of this
assumption, as a result, any attempts to require a new bit moving from
optional to required would fail since the bit would be found, but the
names differed.

055dc233a1 lnwire/features: add required gq to local features
This commit adds the required feature name to our
set of local known features. This will allow other
peers connecting to us to set the required gossip
queries feature bit. This is required for the
subsequent commits, which instruct the server to
set the bit depending on user configured preferences.

1633ab180f lnwire: New API for feature vectors.
This is a rewrite of feature vectors in lnwire. This has a few
benefits:

1) a simpler interface
2) separate structs for a plain set of feature bits and a feature
vector with associated feature names
their respective feature sets
3) loosened requirements that bits MUST be assigned in pairs
4) fix endianness of encoding/decoding

d65f17f1b1 fuzzing: fixed calculation of serializedSize() in features.go
This commit fixes an incorrectly calculated size of a
*FeatureVector in the serializedSize() function. go-fuzz
found that when calling NewFeatureVectorFromReader, if
a flag is invalid, it is not added to f.flags. However,
it will skip the index that wasn't included. This
becomes a problem when serializedSize() calculates the
length of f.flags via len() which can lead to an index
out of range since certain flags may be missing.

lnwire: use ReadFull instead of Read when parsing feature vectors
This commit fixes a bug lingering in the decoding of the feature
vectors which was masked by the prior method of reading the _entire_
message from the stream before parsing it. The issue was that
performing a zero-byte Read on an io.Reader that’s purely streaming
will result in an indefinite block. We fix this bug by properly using
io.ReadFull in this context.

lnwire: remove String() method from FeatureVector
This commit removes the String() method from the FeatureVector as it
can produce confusing output when revving a feature vector and not
knowing the strip mapping ahead of time.

'init' message is the first message reveals the features supported or required
by this node. Nodes wait for receipt of the other's features to simplify error
diagnosis where features are incompatible. This message will help negotioate the
the features which are supported by both sides.
