- * Issues to be discussed:
- * - Return values. There are nonstandard return values defined and used
- * in the source code. This is because RFC2553 is silent about which error
- * code must be returned for which situation.
- * - IPv4 classful (shortened) form. RFC2553 is silent about it. XNET 5.2
- * says to use inet_aton() to convert IPv4 numeric to binary (alows
- * classful form as a result).
- * current code - disallow classful form for IPv4 (due to use of inet_pton).
- * - freeaddrinfo(NULL). RFC2553 is silent about it. XNET 5.2 says it is
- * invalid.
- * current code - SEGV on freeaddrinfo(NULL)
- * Note:
- * - We use getipnodebyname() just for thread-safeness. There's no intent
- * to let it do PF_UNSPEC (actually we never pass PF_UNSPEC to
- * getipnodebyname().
- * - MOZILLA: Thread safeness for pre-Honeycomb Android versions implemented by
- * way of open/gets/close and mmap rather than fopen/fgets/fclose. Affects
- * _files_getaddrinfo for hosts file. Note: Honeycomb and later versions use
- * a thread-safe stdio, so for those versions normal Bionic libc getaddrinfo
- * is used.
- * - The code filters out AFs that are not supported by the kernel,
- * when globbing NULL hostname (to loopback, or wildcard). Is it the right
- * thing to do? What is the relationship with post-RFC2553 AI_ADDRCONFIG
- * in ai_flags?
- * - (post-2553) semantics of AI_ADDRCONFIG itself is too vague.
- * (1) what should we do against numeric hostname (2) what should we do
- * against NULL hostname (3) what is AI_ADDRCONFIG itself. AF not ready?
- * non-loopback address configured? global address configured?
- * - To avoid search order issue, we have a big amount of code duplicate
- * from gethnamaddr.c and some other places. The issues that there's no
- * lower layer function to lookup "IPv4 or IPv6" record. Calling
- * gethostbyname2 from getaddrinfo will end up in wrong search order, as
- * follows:
- * - The code makes use of following calls when asked to resolver with
- * ai_family = PF_UNSPEC:
- * getipnodebyname(host, AF_INET6);
- * getipnodebyname(host, AF_INET);
- * This will result in the following queries if the node is configure to
- * prefer /etc/hosts than DNS:
- * lookup /etc/hosts for IPv6 address
- * lookup DNS for IPv6 address
- * lookup /etc/hosts for IPv4 address
- * lookup DNS for IPv4 address
- * which may not meet people's requirement.
- * The right thing to happen is to have underlying layer which does
- * PF_UNSPEC lookup (lookup both) and return chain of addrinfos.
- * This would result in a bit of code duplicate with _dns_ghbyname() and
- * friends.

The bits labelled 'x', 'p', and 'g' are feature flags.
The bit labelled 'x' is 1 if the build is for an x86 architecture and 0
otherwise, which means the build is for an ARM architecture. (Fennec no
longer supports ARMv6, so ARM is equivalent to ARMv7 and above.)
The bit labelled 'p' is a placeholder that is always 0 (for now).
- The bit labelled 'g' is 1 if the build is an ARM build targeting API 15+
- and 0 otherwise, which means the build targets Android API 9-10 (Gingerbread).
+ Firefox no longer supports API 14 or earlier.
- Fennec no longer supports Android API 8 or earlier. After Bug 1155801 it
- no longer supports API 11-14. API 9 is still supported due to significant usage.
+ This version code computation allows for a split on API levels that allowed
+ us to ship builds specifically for Gingerbread (API 9-10); we preserve

+ At present, the bit labelled 'g' is 1 if the build is an ARM build

We throw an explanatory exception when we are within one calendar year of
running out of build events. This gives lots of time to update the version
scheme. The responsible individual should then bump the range (to allow
builds to continue) and use the time remaining to update the version scheme
via the reserved high order bits.
N.B.: the reserved 0 bit to the left of the highest order 't' bit can,
