Kirill Smelkov f675967c54 Let SQLite use pread/pwrite 
With current settings SQLite was using lseek/read syscalls to read data, e.g.:

	20:43:17.640660 fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0
	20:43:17.640683 fcntl(3, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=1073741824, l_len=1}) = 0
	20:43:17.640705 fcntl(3, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=1073741826, l_len=510}) = 0
	20:43:17.640725 fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=1073741824, l_len=1}) = 0
	20:43:17.640744 stat(".../neo.sqlite-journal", 0x7ffef2c91080) = -1 ENOENT (No such file or directory)
	20:43:17.640764 lseek(3, 24, SEEK_SET)  = 24
	20:43:17.640779 read(3, "\0\0\0\33\0\0\10\235\0\0\10]\0\0\0\27", 16) = 16
	20:43:17.640795 stat(".../neo.sqlite-wal", 0x7ffef2c91080) = -1 ENOENT (No such file or directory)

but if we allow it to use pread it will be only 1 system call instead of 2 and
reading this way can also be done in parallel because there is no global to
file seeking:

	20:48:42.668466 fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0
	20:48:42.668501 fcntl(3, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=1073741824, l_len=1}) = 0
	20:48:42.668522 fcntl(3, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=1073741826, l_len=510}) = 0
	20:48:42.668542 fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=1073741824, l_len=1}) = 0
	20:48:42.668561 stat(".../neo.sqlite-journal", 0x7ffdbc1f22c0) = -1 ENOENT (No such file or directory)
	20:48:42.668580 pread64(3, "\0\0\0\33\0\0\10\235\0\0\10]\0\0\0\27", 16, 24) = 16
	20:48:42.668597 stat(".../neo.sqlite-wal", 0x7ffdbc1f22c0) = -1 ENOENT (No such file or directory)

(if needed this enablement can be done per OS)

Kenneth Shaw 7174000f77 Move RegisterAggregator implementation 
The SQLiteConn.RegisterAggregator implementation was defined in
sqlite3_trace.go file, which is guarded with a build constraint. This
change simply moves RegisterAggregator to the main sqlite3.go file,
and moves accompanying unit tests.

The rationale for this move is that it was not possible for downstream
using packages to use RegisterAggregator without also specifying (and
notifying the user) the 'trace' build tag.
