[Backport candidate] On windows, open cached-routers with the sharing mode "FILE_SHARE_READ so that other processes can read it while Tor is running. (Reported by Janbar).

Track the number of connection_t separately from the number of open sockets. It is already possible to have connections that do not count: resolving conns, for one. Once we move from socketpairs to linked conns, and once we do dns proxying, there will be lots of such connections.

Apply patch from coderman: have posix subthreads mask out signals. This could prevent some kinds of crashes when subthreads try to handle SIGPIPEs and die in the attempt. Backport candidate.

Move all struct-offset-manipulation macros into util.h, and use them consistently. Because there are days when "SUBTYPE_P(handle, subtype, _base)" is just easier to read and write than "(basetp*)(((handle) - STRUCT_OFFSET(subtype, _base))".
svn:r9592
Handle errors on opening cached-routers* more uniformly and sanely: log not-found errors at level INFO, and all other errors at level WARN. Needs testing on win32.

Removing the last DOCDOC comment hurt so much that I had to use Doxygen to identify undocumented macros and comments, and add 150 more DOCDOCs to point out where they were. Oops. Hey, kids! Fixing some of these could be your first Tor patch!

Fix a couple of obvious bugs in tor_mmap_file on Windows: first, fix a boolean error when checking the return value of CreateFileMapping. Second, CreateFileMapping is documented to return NULL on failure.

Try to compile with fewer warnings on irix64's MIPSpro compiler /
environment, which apparently believes that:
- off_t can be bigger than size_t.
- only mean kids assign things they do not subsequently inspect.
I don't try to fix the "error" that makes it say:
cc-3970 cc: WARNING File = main.c, Line = 1277
conversion from pointer to same-sized integral type (potential portability
problem)
uintptr_t sig = (uintptr_t)arg;
Because really, what can you do about a compiler that claims to be c99
but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
is safe?
svn:r8948
Add unit tests for tor_mmap_file(); make tor_mmap_t.size always be the size of the file (not the size of the mapping); add an extra argument to read_file_to_str() so it can return the size of the result string.
svn:r8762
Do not graciously increase the size to be mmaped if the current size already is
at a page_size boundary. This is important since if a file has a size of zero
and we mmap() it with length > 0, then accessing the mmaped memory area causes
a bus error. However, if we pass a length of 0 to mmap() it will return with -1
and things work from there.

spawn_func fixes: have cpuworker_main and dnsworker_main confirm to the right interfaces [casting func to void* is icky]. Also, make pthread_create() build without warnings.
svn:r8327
- made configure link to required system dll's if building for win32
- added diffs for libevent 1.1b
- forced user to turn off eventdns if win32 is set
- cleaned up tor_mmap_file()_win32 (not sure if it's stable)
- cleaned up some warnings and typos

possible. Cache at the server side independently from the TTL, to
prevent attackers from probing the server to see who has been asking
for what hostnames. (Hi, Dan Kaminski!)
Also, clean some whitespace.
svn:r6526
This is needed because Windows already has an err() that we
can't clobber. And we need to be able to make the log functions
a macro so we can print the function's name in the log entry.
