Improve

Improve the compatibility of xdl_iterate_phdr() on Android 4.x.

The first LOAD segment of ELF may be read-only (use the linker option --rosegment), and the /proc/self/maps at this time may look like this:

75b8d000-75b9f000 r--p 00000000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so
75b9f000-75bde000 r-xp 00012000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so
75bde000-75be1000 r--p 00051000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so
75be1000-75be2000 rw-p 00054000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so

In Android 4.x, xdl_iterate_phdr() in previous versions of xDL will not recognize the above libquick.so.

改进

改进 xdl_iterate_phdr() 在 Android 4.x 中的兼容性。

ELF 的第一个 LOAD segment 可能是只读的（用链接器选项 --rosegment），此时的 /proc/self/maps 大概是这样的：

75b8d000-75b9f000 r--p 00000000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so
75b9f000-75bde000 r-xp 00012000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so
75bde000-75be1000 r--p 00051000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so
75be1000-75be2000 rw-p 00054000 b3:1c 89884 /data/app-lib/io.hexhacking.xdl.sample-2/libquick.so

在 Android 4.x 中，此前版本 xDL 中的 xdl_iterate_phdr() 会无法识别到上面的 libquick.so。
