373d9aff7a Fail if file is too large to mmap. 
If tor_mmap_file is called with a file which is larger than SIZE_MAX,
only a small part of the file will be memory-mapped due to integer
truncation.

This can only realistically happen on 32 bit architectures with large
file support.

6aac6c6bee Make ed25519_fmt() log 0-valued keys more nicely. 
Because <unset> makes more sense than AAAAAAAAAAAAAAAAAAA...

(I have indeed verified that ed25519_fmt() is only used for
logging. This patch also clarifies the intention that ed25519_fmt()
is only for logging.

Closes ticket 21037.

a757f76967 Withstand failures in CLOCK_MONOTONIC_COARSE 
This came up on #21035, where somebody tried to build on a linux
system with kernel headers including CLOCK_MONOTONIC_COARSE, then
run on a kernel that didn't support it.

I've adopted a belt-and-suspenders approach here: we detect failures
at initialization time, and we also detect (loudly) failures later on.

Fixes bug 21035; bugfix on 0.2.9.1-alpha when we started using
monotonic time.

f3d056ab16 clarify debug-level log while initializing entropy 
I got confused when I saw my Tor saying it was opening a file
that doesn't exist. It turns out it isn't opening it, it's just
calling open() on it and then moving on when it's not there.

2a00110e5b Revert "Stop checking whether environ is declared." 
This reverts commit 954eeda619.

Apparently, OpenBSD is what expects you to declare environ
yourself.  So 19142 is a wontfix.

1d52ac4d3f Lay down some infrastructure for bridges in the New Guard Order. 
This includes:
  * making bridge_info_t exposed but opaque
  * allowing guards where we don't know an identity
  * making it possible to learn the identity of a guard
  * creating a guard that lacks a node_t
  * remembering a guard's address and port.
  * Looking up a guard by address and port.
  * Only enforcing the rule that we need a live consensus to update
    the "listed" status for guards when we are not using bridges.

954eeda619 Stop checking whether environ is declared. 
There seems to be pretty good evidence that it's always declared,
and that checking for it is pointless.

It's not okay to use the same varargs list twice, and apparently
