3942a116e4 docs: Make various README.md files consistent.
First, it removes the documentation section from all the README.md files
and instead puts a web-based godoc badge and link at the top with the
other badges.  This is being done since the local godoc tool no longer
ships with Go by default, so the instructions no longer work without
first installing godoc. Due to this, pretty much everyone uses the
web-based godoc these days anyways.  Anyone who has manually installed
godoc won't need instructions.

Second, it makes sure the ISC license badge is at the top with the other
badges and removes the textual reference in the overview section.

Finally, it's modifies the Installation section to Installation and
Updating and adds a '-u' to the 'go get' command since it works for both
and thus is simpler.

761381066d txscript: Add new verification flags.
This commit adds two new verification flags to txscript named
ScriptVerifyStrictEncoding and ScriptVerifyDerSignatures.

The ScriptVerifyStrictEncoding flag enforces signature scripts
and public keys to follow the strict encoding requirements.

The ScriptVerifyDerSignatures flag enforces signature scripts
to follow the strict encoding requirements.

These flags mimic Bitcoin Core's SCRIPT_VERIFY_STRICTENC and
SCRIPT_VERIFY_DERSIG flags and brings the Bitcoin Core test scripts up
to date.

f6a437d4c9 btcec: Optimize pre-computed table load.
This commit modifies the pre-computed table used to optimize the secp256k1
scalar multiplication to a string instead of a byte slice.  This change
makes the compile more efficient since the Go compiler internally
represents bytes slices inefficiently.

This reduces the memory needed to compile btcec to 3MB versus the previous
40MB before this change.

In addition, it modifies the code which loads the pre-computed table to
deserialize directly into the table instead of into locals that are then
copied.

Fixes #297.

2713c8528d Consistency and general cleanup in btcec.
This commit contains various modifications for code and comment
consistency in the btcec package:
- Call out references at the top and reference them by their identifier in
  the other comments
- Remove a TODO that no longer applies
- Add comments to the fields in the KoblitzCurve struct and reorder them
  slightly
- Make comments wrap to 80
- Cleanup code that was far exceeding col 80 (only function declarations
  typically do this)
- Extend block comments to use as much of the 80 cols as available
- Add a bit more explanation in a couple of places
- Update copyright year on secp256k1.go
- Fix a couple of typos in the comments

4b84bd52dd Move the btcec benchmarks into the main package.
The benchmarks are still only compiled when running 'go test' so this has
no effect on regular usage.  This is being done because benchmarks often
need access to internal state.

Normal tests are kept in a separate package since they also serve to
exercise the public API, and by intentionally making it more difficult to
reach into the internals, it helps ensure the public API is sanely usable.

Since the benchmarks can now access the internals directly, this commit
also removes the functions which exposed the internals to the test package
from internal_test.go which were only used by the benchmarks.

Also, it removes a duplicate benchmark.

555778e9d5 Don't ignore errs setting consts in btcec init.
This commit converts the initialization of the constants to use a function
which panics on error instead of just ignoring the error.  This is
acceptable since they are hard-coded constants and should never fail.

2b25107317 Add generation code for the endomorphism vectors.
This commit adds code which generates the linearly independent vectors
used by the secp256k1 endomorphism code.  These value are hard-coded into
the curve already, but having the code used to generate them is handy
should any future curves be added which can also make use of the same
class of endomorphism.
