Nick Mathewson 7036ed3471 Fix a couple more long warning lines
These are not a problem with 2-space indentation, but cocci will
start getting confused when clang-format wraps them with 4-space
indentation.

markdown understand our output here.

Nick Mathewson 51a9892914 doxygen: Take "lib" descriptions from doc/HACKING/design.
This commit takes descriptions for src/lib and moves them into our
doxygen hierarchy.  I've covered everything from lib/cc through
lib/sandbox here.

Nick Mathewson 7fc077ed25 Add stub directory-level documentation for most source directories
This includes app, core, feature, lib, and tools, but excludes
ext, test, and trunnel.

This was generated by the following shell script:

cd src
for dname in $(find lib core feature app tools -type d |grep -v \\.deps$); do
    keyword="$(echo "$dname" |sed -e "s/\//_/" )"
    target="${dname}/${keyword}.dox"
    echo "$target"
    cat <<EOF >"$target"
/**
@dir ${dname}
@brief ${dname}
**/
EOF

    git add "$target"
done

Nick Mathewson 0891a31ad3 madvise: tolerate EINVAL and ENOSYS when minherit fails
These errors can occur if we are built on a system with support for
madvise(MADV_NOFORK) but then we are run on a system whose kernel
does not support that flag.

If the error is something that we don't tolerate at all, we now log
it before crashing.

Fixes bug 31696.  I am calling this a bugfix on 0.4.1.1-alpha, where
we actually started using the map_anon code.

This is similar to, but not the same as, the fix for #31570.

This mechanism isn't perfect, and sometimes it will guess wrong,
but it will help our automation.

Nick Mathewson 12205c3cbe Make map_anon expose the result of a noinherit attempt
Previously we did this for tests only, but it's valuable for getting
proper fork behavior in rand_fast.

Nick Mathewson 065e7da8e6 Re-enable and fix unit test for nofork mappings
This test was previously written to use the contents of the system
headers to decide whether INHERIT_NONE or INHERIT_ZERO was going to
work.  But that won't work across different environments, such as
(for example) when the kernel doesn't match the headers.  Instead,
we add a testing-only feature to the code to track which of these
options actually worked, and verify that it behaved as we expected.

Closes ticket 29541; bugfix not on any released version of Tor.

Nick Mathewson 8ca808f81d Code for anonymous mappings via mmap() or CreateFileMapping().
Using an anonymous mmap() is a good way to get pages that we can set
kernel-level flags on, like minherit() or madvise() or mlock().
We're going to use that so that we can make uninheritable locked
pages to store PRNG data.
