64149353dd dos: Initial code of Denial of Service mitigation
This commit introduces the src/or/dos.{c|h} files that contains the code for
the Denial of Service mitigation subsystem. It currently contains basic
functions to initialize and free the subsystem. They are used at this commit.

The torrc options and consensus parameters are defined at this commit and
getters are implemented.

cbc465a3d1 Simplify explicit conditional checks into an inlined function.
This patch lifts the check for whether a given log file (`logfile_t`) is
an "external logfile" (handled by an external logging system such as
syslog, android's logging subsystem, or as an external C callback
function) into a function on its own.

b0b8f7c30c Add support for Android's logging subsystem.
This patch adds support for Android's logging subsystem in Tor. When
debugging Android applications it is useful to be able to collect
information about the application running on the platform via the
various system services that is available on the platform.

This patch allows you to add "Log notice android" to your torrc and have
Tor send everything above and including the notice severity to Android's
ring buffer which can be inspected using the 'adb logcat' program.

5927ed8d33 checkSpace.pl now forbids more identifiers.
The functions it warns about are:
  assert, memcmp, strcat, strcpy, sprintf, malloc, free, realloc,
  strdup, strndup, calloc.

Also, fix a few lingering instances of these in the code. Use other
conventions to indicate _intended_ use of assert and
malloc/realloc/etc.

f74916a98f setup_capture_of_logs: no longer suppress log messages
Previously setup_capture_of_logs would prevent log messages from
going to the console entirely.  That's a problem, since sometimes
log messages are bugs!  Now setup_capture_of_logs() acts sensibly.

If you really do need to keep a message from going to the console
entirely, there is setup_full_capture_of_logs().  But only use that
if you're prepared to make sure that there are no extraneous
messages generated at all.

These appeared on some of the Jenkins platforms. Apparently some
GCCs care when you shadow globals, and some don't.

53a3b39da1 Add -Wmissing-variable-declarations, with attendant fixes
This is a big-ish patch, but it's very straightforward.  Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it.  The cases where we
violated this rule fall into three roughly equal groups:
  * Stuff that should have been static.
  * Stuff that was global but where the extern was local to some
    other C file.
  * Stuff that was only global when built for the unit tests, that
    needed a conditional extern in the headers.

The first two were IMO genuine problems; the last is a wart of how
we build tests.

1cf0d82280 Add SyslogIdentityTag
When logging to syslog, allow a tag to be added to the syslog identity
("Tor"), i.e. the string prepended to every log message.  The tag can be
configured by setting SyslogIdentityTag and defaults to none.  Setting
it to "foo" will cause logs to be tagged as "Tor-foo".  Closes: #17194.

8cb5070376 Use C99 variadic macros when not on GCC.
1) We already require C99.

2) This allows us to support MSVC again (thanks to Gisle Vanem for
   this part)

3) This change allows us to dump some rotten old compatibility code

7bed9dc73a Avoid double-parens in log_fn() messages on clang.
On clang (and elsewhere?) __PRETTY_FUNCTION__ includes parenthesized
argument lists.  This is clever, but it makes our old "%s(): " format
look funny.

This is a fix on 0957ffeb, aka svn:r288.  Fixes bug 15269.

93dfb12037 Remember log messages that happen before logs are configured
(And replay them once we know our first real logs.)

This is an implementation for issue 6938.  It solves the problem of
early log mesages not getting sent to log files, but not the issue of
early log messages not getting sent to controllers.
