Previously it looked for the debuginfo object for "/system/X" in
"/sdcard/symbols/system/X". This commit removes the requirement for
"system" as the first path component, so the mapping is now "/X" (viz,
any absolute path) to "/sdcard/symbols/X".

These holes are not initialized,
and writing these uninitialised bytes to the mapped file
causes an error being reported when running Valgrind
inside Valgrind. Having no holes avoid having this error.

functions that do FP arithmetic. This is due to the Dwarf3 CFI
mentioning Dwarf registers above N_CFI_REGS, in particular FP
registers, which have values of about 80. This fixes the problem by
increasing N_CFI_REGS to a level that covers all known registers.

(that holds partially defined bytes), to GC more aggressively.
Details in the comments. This largely avoids a sometimes massive
space leak, that has been observed (eg) running the Firefox test suite
on Memcheck. Without this patch it cannot complete with 4 million
nodes in the table; with the patch it completes comfortably with 50000
ish nodes. This reduces the total memory use needed for the run
from above 7GB down to 6.2GB.
Smaller improvements have been seen with other programs too. Speed
does not appear to be negatively affected.
