aa971c5924 Move our "what time is it now" compat functions into a new module 
I'm not moving our "format and parse the time" functions, since
those have been pretty volatile over the last couple of years.

1135405c8c Fix a variable-shadowing bug in check_private_dir 
We introduded a shadowed variable, thereby causing a log message to
be wrong. Fixes 19578. I believe the bug was introduced by
54d7d31cba in 0.2.2.29-beta.

8ba4ba0a74 Grammar. 
I grepped and hand-inspected the "it's" instances, to see if any
were supposed to be possessive.  While doing that, I found a
"the the", so I grepped to see if there were any more.

265e40b481 Raise libevent dependency to 2.0.10-stable or newer 
Only some very ancient distributions don't ship with Libevent 2 anymore,
even the oldest supported Ubuntu LTS version has it. This allows us to
get rid of a lot of compat code.

Fix bug19483: avoid range checks when they are always true 
Some compilers are smart enough to work out that comparisons to
LONG_MAX are a no-op on L64.

Improve overflow checks in tv_udiff and tv_mdiff 
Validate that tv_usec inputs to tv_udiff and tv_mdiff are in range.

Do internal calculations in tv_udiff and tv_mdiff in 64-bit,
which makes the function less prone to integer overflow,
particularly on platforms where long and time_t are 32-bit,
but tv_sec is 64-bit, like some BSD configurations.

Check every addition and subtraction that could overflow.

Fix an integer overflow bug in the tv_mdiff range check 
The temporary second used for rounding can cause overflow,
depending on the order the compiler performs the operations.

358fc026d9 Remove a ridiculous realloc call from torgzip.c 
realloc()ing a thing in order to try to save memory on it just
doesn't make sense with today's allocators.  Instead, let's use the
fact that whenever we decompress something, either it isn't too big,
or we chop it up, or we reallocate it.

808015316a Remove support for zlib <= 1.1 
zlib 1.2 came out in 2003; earlier versions should be dead by now.

Our workaround code was only preventing us from using the gzip
encoding (if we decide to do so), and having some dead code linger
around in torgzip.c

94762e37b9 Use the Autoconf macro AC_USE_SYSTEM_EXTENSIONS 
The Autoconf macro AC_USE_SYSTEM_EXTENSIONS defines preprocessor macros
which turn on extensions to C and POSIX. The macro also makes it easier
for developers to use the extensions without needing (or forgetting) to
define them manually.

The macro can be safely used because it was introduced in Autoconf 2.60
and Tor requires Autoconf 2.63 and above.
