Use tor_fgets() instead of fgets(). 
This patch changes our use of fgets() to tor_fgets() for more consistent
error handling across different versions of the C library.

c4f2faf301 Don't atoi off the end of a buffer chunk. 
Fixes bug 20894; bugfix on 0.2.0.16-alpha.

We already applied a workaround for this as 20834, so no need to
freak out (unless you didn't apply 20384 yet).

a23fd15786 Fix unreachable heap corruption in base64_decode() 
Give size_mul_check() external linkage and use it in base64_decode() to
avoid a potential integer wrap.

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.

Fix bug19483: avoid range checks when they are always true

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,

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.
