6c8c973191 Rename the hybrid_encrypt/decrypt functions; label them as dangerous
We need to keep these around for TAP and old-style hidden services,
but they're obsolete, and we shouldn't encourage anyone to use them.
So I've added "obsolete" to their names, and a comment explaining
what the problem is.

Closes ticket 23026.

db1664e593 Improve comment about why we disable TLS compression.
Closes bug 22964.  Based on Teor's replacement there, but tries
to put the comment in a more logical place, and explain why we're
actually disabling compression in the first place.

10331081c7 test: Remove buggy unit test in test_hs_service
There isn't much of a point of this buggy test afterall to add twice the same
service object but with a different key which ultinately can end up failing
the test because 1/N_BUCKETS of probability that we end up to put the service
in the same bucket.

Fixes #23023

Fix and expand upon our Travis CI configuration.
* CHANGE .travis.yml so that commands for different purposes (e.g. getting
   dependencies, building, testing) are in separate config lines and sections.
 * CHANGE .travis.yml to use their mechanism for installing dependencies via
   apt. [0]  This also allows us to not need sudo (the "sudo: false" line).
 * CHANGE Travis CI tests (the "script:" section) to build and run tests in the
   same manner as Jenkins (i.e. with --enable-fatal-warnings and
   --disable-silent-rules and run `make check`).
 * ADD Travis configuration to do all the target builds with both GCC and clang.
 * ADD make flags to build with both of the cores available.
 * ADD notifications for IRC, and configure email notifications (to the author
   of the commit) only if the branch was previously building successfully and
   the latest commit broke it.
 * ADD the ability to run the Travis build matrix for OSX as well, but leave it
   commented out by default (because it takes roughly ten times longer, due to a
   shortage of OSX build machines).
 * ADD Travis config option to cancel/fail the build early if one target has
   already failed ("fast_finish: true").
 * ADD comments to describe what our Travis config is doing and why it is
   configured that way.

2ae51ed5e2 Fix zstd 1.3.0 trouble: Be more respectful of its state machine
In zstd 1.3.0, once you have called ZSTD_endStream and been told
that your putput buffer is full, it really doesn't want you to call
ZSTD_compressStream again.  ZSTD 1.2.0 didn't seem to mind about
this.

This patch fixes the issue by making sure never to call
ZSTD_endStream if there's any more data on the input buffer to
process, by flushing even when we're about to call "endStream", and
by never calling "compress" or "flush" after "endStream".

b7566d465f Fix a signed integer overflow in dir/download_status_random_backoff
Fix for 22924. Bugfix on 0.2.9.1-alpha when the test was introducd
-- though it couldn't actually overflow until we fixed 17750.

Additionally, this only seems to overflow on 32-bit, and only when
the compiler doesn't re-order the (possibly dead) assignment out of
the way.  We ran into it on a 32-bit ubuntu trusty builder.

3cec1783b7 Fix compiler warnings with openssl-scrypt/libscrypt test on clang
Clang didn't like that we were passing uint64_t values to an API
that wanted uint32_t.  GCC has either not cared, or has figured out
that the values in question were safe to cast to uint32_t.

Fixes bug22916; bugfix on 0.2.7.2-alpha.

c086a59ea1 prop224: Configure v3 service from options
This commit adds the support in the HS subsystem for loading a service from a
set of or_options_t and put them in a staging list.

To achieve this, service accessors have been created and a global hash map
containing service object indexed by master public key. However, this is not
used for now. It's ground work for registration process.

765ed5dac1 prop224: Add a init/free_all function for the whole subsystem
Introduces hs_init() located in hs_common.c which initialize the entire HS v3
subsystem. This is done _prior_ to the options being loaded because we need to
allocate global data structure before we load the configuration.

The hs_free_all() is added to release everything from tor_free_all().

Note that both functions do NOT handle v2 service subsystem but does handle
the common interface that both v2 and v3 needs such as the cache and
circuitmap.

02e2edeb33 prop224: Add hs_config.{c|h} with a refactoring
Add the hs_config.{c|h} files contains everything that the HS subsystem needs
to load and configure services. Ultimately, it should also contain client
functions such as client authorization.

This comes with a big refactoring of rend_config_services() which has now
changed to only configure a single service and it is stripped down of the
common directives which are now part of the generic handler.

This is ground work for prop224 of course but only touches version 2 services
and add XXX note for version 3.
