There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes
The OpenSSL "RSA" object is currently 408 bytes compares to the ASN.1 encoding
which is 140 for a 1024 RSA key.
We save 268 bytes per descriptor (routerinfo_t) *and* microdescriptor
(microdesc_t). Scaling this to 6000 relays, and considering client usually
only have microdescriptors, we save 1.608 MB of RAM which is considerable for
mobile client.
This commit makes it that we keep the RSA onion public key (used for TAP
handshake) in ASN.1 format instead of an OpenSSL RSA object.
Changes is done in both routerinfo_t and microdesc_t.

also add tests for bw_file_headers.
Headers are all that is found before a correct relay line or
the terminator.
Tests include:
* a empty bandwidth file
* a bandwidth file with only timestamp
* a bandwidth file with v1.0.0 headers
* a bandwidth file with v1.0.0 headers and relay lines
* a bandwidth file with v1.1.0 headers and v1.0.0 relay lines
* a bandwidth file with v1.0.0 headers, malformed relay lines and
relay lines
* a bandwidth file with v1.0.0 headers, malformed relay lines,
relay lines and malformed relay lines
* a bandwidth file with v1.1.0 headers without terminator
* a bandwidth file with v1.1.0 headers with terminator
* a bandwidth file with v1.1.0 headers without terminator and
relay lines
* a bandwidth file with v1.1.0 headers with terminator and relay
lines
* a bandwidth file with v1.1.0 headers without terminator, bad
relay lines and relay lines
* a bandwidth file with v1.1.0 headers with terminator, bad relay
lines and relay lines
* add bwlist_headers argument to dirserv_read_measured_bandwidth
in order to store all the headers found when parsing the file
* add bwlist_headers to networkstatus_t in order to store the
the headers found by the previous function
* include the bandwidth headers as string in vote documents
* add test to check that dirserv_read_measured_bandwidth generates
the bwlist_headers
